I used to use a Leaderfins Hyper (NOT the Pro) and use now a GlideFin.
In my opinion the Waterway GildeFin is the much better fin than the Leaderfins Hyper. That in terms of comfort but never the less efficient footpockets as well as in smoothness of the blade movement.
Further special for DYN the Leaderfin is really heavy and negative buoyanced.
If I swim 50m speedies I'm one and a have second faster with the Waterway Glidefin (soft blade) than with the Leaderfin Hyper, Medium Blade. (~22" instead of ~23-24")

PS: The Glidefin on the pic is not mine, I is the quite new one from my girl friend.
My Glidefin is with open heel footpockets and looks a "bit" more used with a lot of scratches and a patched blade ;-)
