I curently ride a 2006 Jaime Pro XL (132 x 42), I weight 185 lbs and ride in winds ranging from 15 km/h to 65 km/h. The Jaime XL works very well even in the nuking winds in big chop (I think because of the flex tips), its a very smooth board compared to my 2004 Jaime Pro L (128 x 37.5)
I have never ridden a board with concave but I am wondering how the bottom end wil compare to my Jaime XL? I imagine it will be a stiffer board with less light wind performance, but the website states the concave reduces the need for a large board width???
What size of board would it compare to with no concave?
