Nah, I don't think so.
If you're riding an old Sims right now, I'm sure it's traditional camber and both of those alternative camber boards should be an easier ride than an old traditional cambered stick. The Proto can be a bit of a challenging ride compared to other alternative cambered boards, but not compared to an old cambered stick.
