I have the 5'4" broadcast and i have 2 brothers over 200lbs. They can get up but can't drop the rope on it behind my 21 mojo. Some might be skill but it's definitely not pushing them hard.
interesting. haven't ridden a broadcast in years but at 220lbs and my sisters ex pushing 250-260 we were both able to freeride that board all day long behind several boats of varying degrees of wave heights.
