I was able to learn to surf on my stock 400lbs on my LSV. Once I upgraded to the 750 it was a lot easier and more fun. My friends dad always told us, no need by buy extra weight, just get some bigger girlfriends. We used the idea of bringing more people to add weight, problem is then you have to let every have their turn. Ballast bags dont want to surf so they are great, hahaha. Mike forgive me if I'm wrong, but I think I bought your old 750s
