Fast forward wheels

Has anyone used any of Fast Forwards wheels? I see the have 50mm and 58mm wheels (wondering if these are the old Zipp 404 rims?). I also see they do a powertap Disk wheel - i am guessing they are the only company so far to do this. I beleive these are the Wheels Torbjorn uses.

Also wonder if anyone know how the X-treme wheels fair aerodynamically. A number of UK testers used them last year and went pretty well. Though I beleive the CTT made the deep front wheel illegal (as will be the Zipp 1080 and Hed 3 deep for UK TT’s).

did you see the price of that PT disc??? heck for that price you’re better off getting a regular disc and an SRM!
