This is an interesting blog to write from the perspective that the progression in the race shapes is moving much quicker than most other board design and has various factors affecting the final design outside of the norm.
These include the perspective of emerging rules for the race category, specifically if you look at “One board rule racing” while considering the variety of conditions one might be racing in.
Another area is the rate at which the riders are improving their skill level to deal with progression in design and what might work best, for the more recreationally oriented rider.
