I'm currently doing research into the feasibility of a 3000 boomilever but I would say that 3000 is a stretch as currently there has only been one report of a Div. C boom breaking 2k. So far research has been promising but otherwise, nothing stands out. As for Div. B, I would say that a 3000 boom is much more feasible.Do you guys think anyone would come to nationals with 3000 efficiency? or close to it somewhere like 2800-3000?
