Hanging onto the rope isn't surfing . . .

IMO, buying a board based on the size of your wave isn't the way to go about finding the right one. Focus on rider size, ability and preference of surf or skim.

Both the Mondo & Mojo can be surfed with stock ballast but both will produce improved waves very easily by plugging in larger ballast bags. There are some rather simple ways to tie in an IBS to really improve the surf wave on both of these boats.
