Hard to find any info online on these wings for proning into waves.
How hard is it to pump and connect waves the Havocs?
Not exactly what you asked, but I’ve used the 121 behind the boat and the 148 on a lift x. I can pump the lift x for a bit with the 148 so I’d say it pumps ok considering the weight of the liftx and that I just learned to pump. The 121 is very surfy but I haven’t pumped it much yet. The 121 turns great with my 26 carve tail.
not sure if this helps but figured I’d share just in case.
