The SMASH is my personal favourite performance board. Most of my team riders love this board too. I ride it in most good waves, 2 - 6ft. It is smooth and has great drive. The wide point is a more forward than the HPX2 for a higher pivot point and to help with paddle. Rails are low for sensitivity. Bottom is single to double concave with a low entry rocker and some curve in the tail for quick release.
I am 73kg and 5'8''. I ride the SMASH as a 5'9'' x 18 7/8" x 2 3/8" Vol 26.4L
