Ok so I got mine into my SN,with a 9/15 hooker and finally got a chance to try it out Yesterday,its a big difference for sure. When siding out to do 180s, I could feel it hook up much quicker than my old pump.Top end on the ski was big differnce as well acceleration was crazy fast and makes me want my long skegged rideplate back.On the bottom end ski is got some mad hops it will literally blast up out of the water in a way that makes the old pump feel like it was designed for infants to ride with. Heres the bad of it,The ski hooks so good now I was beat up and worn out by the end of the day.My setup is not even that strong,61x with pro tec pipe,head,and ocean pro vortex FA, so I can't imagine how this hits with a real setup or a BB in it. Any body considering this mod should definitely go for it, this pump is worth it for sure.
