Yeah well aside from any contentious debate about who may have come up with this idea first

...
Could someone who's ridden a board with this shape bottom / rail give me a description on the performance characteristics. Does it make driving bottom turns /reo's better or does it enhance control through the whitewater????
I'm guessing you would feel like you could get a little further out over your rail & it would be less likely to catch a rail or tip as someone mentioned previously.
How many degrees difference from a standard flat-bottom would it be, it looks like a pretty subtle difference?
