I know there are one or two older threads that discuss these fins briefly, but I'd appreciate some input from those who own the 80s. A friend and I are going to import some C4 gear in the next couple of weeks and I'll be getting a set of blades for pure freediving (I use matrix blades for spearfishing). I'm a slow diver and the matrix #3s are great for spearfishing but slightly too hard for deep dives on a line.

So, just how soft are the 80s and are they more efficient than the 30s and 40s? I'm a big guy (100kg) and diving with a 5mm suit and a fair bit of lead so I wonder if the 80s will have enough grunt to get me off the bottom?

Cheers
Dave
 
hi,

i use 80's. they are a bit softer than ww #3, if that means anything to you. a friend of mine compared their stiffnes to the 30's. i couldn't say which are more efficient. i definitely like the 80's. mainly for the feel of the long blade. also, my diving technique is based more on relaxation and technique than strength.

hope that helps,

roland

ps: when travelling their length isn't too handy.
 
I have the 40's and love them, although I usually use a monofin now.

A buddy of mine got the 80s and didn't like them as much as the 40s, but can't remember why.

Once comment I ahve heard is that due to the length of the 80s they tend to be difficult to use for dynamic. Turns are harder and they also tend to create drag if you're close to the bottom.

A friend of mine got the 80 and said they were too soft for CW. Knowing you are 100 Kg, I think you won't appreciate them.
He also said the 25 were better ....
 
I have 30's, 40's and 80's, yeah it's a lot but all of them together are still a lot cheaper than trimix diving.

I started with the 40's and loved them- until I got a pair of 30's.

The 40's are now way too stiff for my comfort and spend most of the time in my dive bag. I liked the 30's so much that I decided to take a chance on the 80's. The 80's are much softetr than the 30's and make me wonder what a pair of 25's would feel like.

I use the 30's for spearfishing, but the 80's for everything else. They are my favorite fins of all. If I had to limit myselfto just one pair it would probably be the 80's and I would just deal with them in the shallows. They are a little bit longer than the 30's, but if you are already used to long fins they are not that big of a deal- except when it comes to finding a standard sized dive bag to fit them in since most can barely handle a normal pair of freediving fins.

I like them for dynamic because they kick so easily, but if your pool is shallow they do end up hitting the bottom a bit more than my other fins.

I really like them for constant wieght since they don't tax my legs too much on the way back up. As far as your weight goes that's your call. I weigh around 80kg so am a bit smaller than you and that might figure into it. The one thing I have found out is the longer I freedive with bi-fins the softer I like them. Monofins are another story......

Those are some very helpful comments, thanks guys. It's still a bit of a hard choice without the opportunity to try out any of the blades but like you, Jon, I seem to be needing softer and softer fins the more diving I do and the better my technique gets (from awful to merely poor) so I might take a chance on the 80s.
 
I have been wanting to check out the c-4's, does anyone have any good links to the dealers for this particular fin.
 
Hey Jason:
I think that I know why our buddy didn't like the 80's: cause he got the monofin!

And I agree with you: if we are not talking about monfins, the 40's are great.

Cheers,

Roberto
 
This question was posed in another thread and thought I might ask here too. What are the advantages of the c4 flap over the standard c4 or have they even been out long enough for most to have tried them yet.
 
I have the flap 80 AND the flap 30 so if you live in Sweden you could come and try them.

The flap 80 is really soft but a nice fin if you have relaxed slow kicking technique. Have not tried the 30 flap yet.
 
PoseidonSv, Thanks very much for the offer. I would have a very long flight to come see you as I live in Florida US. It is good to hear someone has tried and likes them very much though. I would be interested to hear from one of their engineers the theory behind the cut out protrusions at the fins distal end. I'm thinking it probably effects the way the water streamlines off the end of the fin and prevents spooning?
 
Hi there everyone,

The Falcon 30's and mullins 80's arrived here in NZ fine and we were very impressed with them. they felt so comfortable that you hardly noticed they was there, but you wizzed along the pool.

We got some videos last nite of the Faclon 30's and 80's, here is ther link to view both of these on the homepage, one is doplhin kick fast and the other is bi kick at mullins normal pace. over time we will video other fins in as much controled condition as possible to give people a visual refernce of what it will perform like if they cant rty before they by.


Also comparision to a apair of plastic fin bldes

I broke down and ordered 80s with the flap. I had trouble at first overpowering them but eased up. They give acceptable accelleration, and after about the 5th stroke you are flying. 1-2 monofin kicks to get started seem the best.
I weigh ~210 lb and feel comfortable with them. I have only been in the pool with them but will hit the ocean in a week or 2. I don't forsee much trouble at depth just off the feel of the fin. I am used to Picasso black and esclapez green, so this is a whole new feel. They would suck for spearfishing as they only want to drive forward and not get sideways at all.

The form flaw I'm fighting is letting my toe overpower the outside of my foot, I didn't know I did that before but if I do now I get pigeon toed and the fins bump at the center. If I lighten the stroke or order my feet to push with the outside edge it clears up but is not %100 natural yet.

It's tough overcoming my desire to push hard, but it does not help my speed much and costs much more air/time. I get so psyched hitting in the ballpark of monofins speed with a bifin that I get overexcited and caught up in max speed. I'll calm down eventually.

They seem as different from the bifins I have used as mono did.
 
I had exactly the same experience, I also have a pair of Picasso Black team and that is the best plastic fin i have but the C4 Flap 80 is different and better.

As you say I also noticed dolhinkick is good way to get speed, at first it felt like i was going slow but its just the kicking that is slow because when id did my lengthdives underwater i noticed i travelled far greater distance than what it had felt like when i was swimming underwater. I weight 165 lb and they work fine for me.

They take me further with less difficulty for sure!
I had tendency that the fins wanted to slip and slide inwards so the blades almost touched eachother.

Definitely with such excellend LOOONG carbon blades you have to relearn and start to kick slow deep kicks because you will get there easier and with less effort it just feels a bit slow.
