The problem with a stock only hull and bond rail is that it would kill the idea of progression. Some guy puts a carter b rocker on his superjet or buys a rickter surf ski and they get kicked out of the class.
I have spent my fair share working on composites, and its sometimes cheaper to buy an am hull than modify a stocker. Time does have value.
It may be best left up to the judges. Weigh and measure the skis, deduct points for flip and spin tricks on shorter skis and add them back on nose tricks. Lihtweight hulls get deductions for aerials while waterlogged stockers with a bunch of glass work get a bonus. Jve never been a judge, so i dont know if that is feasable.
Goal should make barrier to entry absolutely minimal, while figuring out a way to keep people in it as long as possible, while keeping the freedom to modify as they please.
Again, i cant compete anymore, but i was practicing and this was my thoughts. I wanted to race and freestyle the same boat becauxe i didnt have money for 2 and it created this conundrum of not fitting in anywhere.
