Thanks for the reply. I agree with you...realistically I think volume wise I fall I between both the 5'4" and 5'6" (a custom would probably be the ideal route--but I do like the feel of a parabolic ). Further, yea thickness is a factor, but really I focus on the overall foil of a board- 2 1/4" isn't always 2 1/4"--hence the volume emphasis of Chris above. Looking at some of DTs other shapes his foil seems a bit fuller...nose to tail. So in my mind getting a better sense of the overall dimensions would give me perspective on the area of the planing surface in the nose...given the parallel rails I'm sure it's wide but I'm game for that and think it will compliment the height/width factor.
To be honest, my last board was the only one I bought otr. Usually, I can manage these types of question whether by looking at a similar board, talking w a friend who owns one, etc. there is nothing like the vanguard and therefore I want to be really informed prior to dropping a bunch of money on a board. So hence the really specific questions. I started calling some local shops and hoping one of them has one of these boards to look at it. If I can get a tape on one ill post up some dims...
Thanks for the help and perspective...I do appreciate it!
