Here is my short opinion on my full fins. They are Tusa split fins. I dive with the Scuba Pro Twin Jets open heel. These are my first pair fo full foots, and I have yet to use them. They seem to be alittle stiffer than the SP fins. I wanted a pair of full foots, but just waited. I bought these for $15 new, marked down from $75(I think). It was one of those daily specials on Leisure Pro during the holidays. Itching to try them out. They seem to be of good quality and come with a 3 year warranty.
