If I had a possibility to choose a handmade monofin for freediving, what kind of should it be?
Ofcourse there is some limitations of the design:

1. Fiberglass blade made from very thin layers. (maybe the
term is "Tapered"). This means there is more layers near
footpockets, and in the end part of the blade there is
less layers, this means the blade is softer in the end.
My current mono has 11 layers, it is classified as medium
stiffness in Sebak terms.

2. Maximum size is 100cm x 100cm.
(My current mono is 75cm x 75cm.)

Most of the monofins I have seen are made for finswimming.
In finswimming the blade is smaller and very stiff in
short distances (the shortest distance is 50m).
The biggest finswimming competition distance (as far as I know) is 1500m.
In bigger distances the blade is bigger and softer. But even in long distance finswimming the speed of the swimmer is much faster than in freediving.

When diving dynamic in the pool with my mono, sometimes the
blade bends in wrong direction. This means that it seems to be
V-shaped when looked from the back. My normal dynamic speed is about one meter per second. I think that maybe
a softer and longer blade would be better.

I know many freedivers use monofin, so please write down
your opinion, what kind of mono do you have, and how would you like to change it, if it were possible.

Thanks, Teppo.
