Fascinating thread.
Interesting to compare the newcommers (like me 2 yrs ago) and the regular monofin users` comments.
What brought me here - sprint fin is definitely not the right place to start.
Older comments - think lot of naive comments re model 1 vs Model 2. Reality is that the fins are built to a pattern, but the end result is so dependant on the particular piece of fibreglass that`s the pattern is applied to. Comparing one particular fin against another is just not meaningful. So many replies just don`t appreciate how variable the raw materials can be.
Established freedivers are right in that you have to buy something and give it a try. What I didn`t notice was them saying is that what is right for you can change very quickly.
Two years ago, Bogdan supplied me with a Model 1 long distance fin which should have been right - I was just over 6 ft, and 84 kilos.
However, one arthritic knee meant that I didn`t have the muscles to even start driving it properly. Bogdan responded by supplying me with an exceptionally fexible long distance model 2 (now I had two fins).
Was away like mad with it, but within 3 months I was building those muscles that only a monofin reaches, and I could start using the model 1. Within another month or two I had set the Model 2 aside - with my building muscles it was now too flexible, and the original model 1 was right for me, though without the model 2, I would never have got there.
Another 9 months later, and that original fin was feeling too soft for my developing muscles, so I bought my present middle distance model 1 (again, for a six-footer, but now with a years worth of monofinning muscles).
This fin is magic for me - an extension of my body - I think I have finally found the fin that will suit me for a long time.
Think I`m agreeing with the earlier post that said buy something in the middle, model 1 if you are big, but model 2 if you are more average. Then just take it from there. If the first one is right for you, it very soon won`t be, but by then it will have done it`s good work on your muscles and you will be ready for the next one.

Oh - on model 1 vs model 2 fin sizes - that special super flexible model 2 which Bogdan supplied me with (and which, incidentally, my daughter is now starting with but with re-built footpockets to fit her high instep, long thin feet) is exactly the same size as my model 1s, but so rediculously flexible.
