Ok, had 2 hrs. light wind stuff on 12m SB, I ride hooked in with both twinny and surf board.
For light conditions where you have to walk, and walk I did...it really is nice. Hooked in floaty tricks are no prob. and it is nice to slide to toe side on landings and transitions.
I also had it out in 25 knots on 9m Rev. on the first session using the Dynabear at Lano.; and then the thing scarred me........the way it jumps about just takes some getting used to I guess, the benefits are there though.
Still need many hours before I can comment on build quality.........I will break this thing sooner or later

And I just had a peak at that video about and it is awful..sorry fellas.
