Hi there, just got a new to me 2010 moomba Mobius LSV boat. I have been trying to surf but can’t go ropeless. It has 750lbs in each rear, ski locker and IBS ballast. Also have wakeshaper. Wondering what set up and speed I should be using? Considering upgrading to 1100 lbs in rear but not too sure they will fit. The size of the 1100s are 50 x 24 x 24 and the 750s I have are 50 x 20 x 20 and they are popping up the compartment when full. Please help!
