I'll weigh in with an EvoII comment.
The soft chine rails up front really allow the board to sit in the wave, and are very stable and forgiving when up front.
But the EvoII has quite a bit of performance off the tail just like the UFO.
Clubted, you mentioned low boxy rails... On the Blewitt... But the rails on all the boards change quite a bit through the length of the board...
Bob also stated that the Ray Gleave has Broomstick Dia rails up front... Most HP's are close to that anyway. But I like that simple statement / reference point...
A few of the boys said I should ride a Ray Gleave, and that I surf like him. Another comment was that I'm a natural longboarder. It's obvious I like to cruise and trim at times. I was quietly flattered. Some of the other boys on the trip rarely moved forward on a 9'1, or only move 1 foot forward.
To be honest I actually can't remember exactly when I last rode anything under 9... Actually it was Chrispy's
