I can't tell you about the other boards.I have been on Jaime pro medium 05', 06',
and now 07'.
Each year they have gotten better, and 07' is no exception!. I am 5'9" tall,
and 140lbs, the board has an asymetrical concave bottom on heelside edge only,
as well as a longer/straighter heelside outline and a shorter curvier toeside outline,
good for toeside bottom turns on waves i have found!.
Rails are square w/ slight bevel starting in front of fins.
The concave bottom makes going upwnd effortless, and the pop is dramaticly increased!.
3 stance options, I use middle holes, which is plenty wide for myself.
Outstanding twintip for sure, but since I got my 07' 5'5" Rocketfish,
the Jaime just collects dust now, (except when tide is so low that is not enough water
for surfboard fins!)
