Bought this after borrowing one from a friend. We are always looking to improve our wave and so far this has been our favorite! We have a 2007 MasterCraft X2 with rear piggyback sacs. This shaper puts out a nice long wave that is tall and long! With our other shaper we had a really steep and shorter wave.This one is perfect! Not sure what the blemish was but don’t really care it spends its life either in a locker or underwater. I also noticed that the suction is really strong. Strong enough I decided not to run a lanyard. The only thing I think could be improved is having the float high visibility so I the off chance it falls off it would be more visible in the water. But so far I don’t think any other brands are doing this.
