Noah, I'm currently using a pair of Sporasub Pure Carbons. I have a pair of Fishers but they cracked at the screw holes. I am in the process of cutting off the angled part at the crack and forming them into new blades - they will end up being just slightly longer than the Pures, which shows how long they are in the first place. If you go with the Powerfins, I would epoxy a tab to the back so that you can use the new Omer footpocket system - no screws.
