It would be nice if people come up with comparisons between different fins, types and brands.
I've now two Waterway fins,
A Model 2, middle distance;
The one I started with, great for intensive, middle to high speed monofinning, but you need more develloped muscles. After two years in hindsight I recomment the model 2 long distance version for beginners, because it's easyer to learn technique with a softer blade.
A model 1 Long distance,
This is my current love, it's big and flexible in the right direction. Allows for slower swimming, more fitting to freediving. It's very price friendly, arround E 140.
I've also recently swam with a Specialfins' Freediving monofin 'dolphin'.
To me it was rubbish, and viewing the owner swim with it he had the same problem of folding the blade. The blade bends in the wrong direction (folds) when swimming. This way very much the energy is lost making it a night and day difference to my Waterway model 1 Long distance. Currently I and the other guy do about a 130m, but as a competitor I fear the day he would have a new monofin. I told him after he tried mine and loved it, that he would do easily a 150+ when he would borrow my fin for a few days. I'm sure he would be very interested in this tread!
More comparisons please,
Love Peace and water!
