I've got a prisk(last years model), goes quicker in your average british surf than my cresent tail thats for sure, not tried it in any proper hollow or slabby waves yet, so can't comment on how it handle those sort of waves. Is also looser on turning, doing 360's etc.
I love bat tails, I always seem to get more speed across slack sections and most UK waves have plenty of those. I've never had any problems with holding an edge with a bat, except in small wedgy surf on a BZ Big Bruddah, which was a bit big for me
So far, I'm loving the bat-tail. I like how you can't be lazy and just turn your back to a wave, paddle and let it happen - got to be more technical, aware, and trim the board, otherwise it's all over the place. That really appeals to me.
Lots more to learn but that was the best session so far this year, even with new, unfamiliar kit.
This board is also a little on the small side for my weight (ideal for my height though). It's 3/4 of an inch shorter than my NMD, and narrower. The reduction in buoyancy was noticeable when paddling - mostly solved by a change in position - but the ride on a smaller board is far, far better, I felt more in control and able to balance. Lesson learned on that front.
