Abri,
I never have a spearo wetsuit with pad. All my suits are always Polartec type cause I get clausterphobia when I wear neoprene even at 2mm.
Somehow my skin is NOT those "rich man" skin that develop rash or bruises from loading a gun, some of my friends do develop some bruises but not me. The Riffe butt is also very comfortable and I load at my tummy where my belly muscle can assist a 4 cm projection.........aka...beer belly
Wha ha ha ha.
However, if after fighting a fish, I sometime get tired loading all the 4 bands on my #4. U know how we bubble blowers are, heavy exertion at 100 feet is not something we enjoy too.
So far so good but I just can't imagine RA butt at that kind of rubber pressure........uuggghhhhh...painful Mom !!!
Murat,
I thought you are smarter than me in the Mori rubber test chart but.............u are not doing any better than me.....
This chart confuse me cause it does not have any unit of measure, I know what the Initial Modulus means but not the power potential.
That Initial Modulus (stretch ability ) and 1 hour after that tells u how much power is lost after the rubber get cocked for an hour. Rubber loose power when cocked too long. I am just trying to read the pound/lbs measure, maybe they are talking of some other measurement in Newton or something, sorry way out of my scope. I am just confused, why bother to prepare a chart without a legend which will guide readers to what numbers they represent.
However there is one point u must remember which is true but not many people realize. Rubbers maybe powerful, say 50 kg pull. We assume that when a shot is made, that 50kg thrust is available to push the shaft. What we must know is that how fast that 50 kg of trust is being given out, how snappy the rubbers are, how fast does it return back to its original non stretch shape. This will define the speed of push available to the shaft. The only way to tell accurately is to chronograph the speed of the shaft when fired or shoot into a ballistic putty to read the penetration.
I used to have a digital chronograph but not for underwater use, it was for my airguns or fire arms. Without a chrono, u can't tell improvement in the speed of the projectiles. Penetration will depend on the spearhead design too, so can not provide accurate data.
There was a case that I had heavier springs for my spring powered airgun. It was a brute to cock but the result was not good on the chrono. The science lies in how fast the spring re-coil back to its shape and generate that thrust. Without a chrono, all I could tell was the amount of recoil on the gun and falsely felt that it was more powerful, but actualy no power gain over the original softer spring....
The new Air Arms custom spring by a British genius proved this, he made such a wonderful spring, soft to install and low recoil but the power it produced is amazing. Science my friend science.
