i do exactly what everyone is saying to do when it comes to cutting into the wake and all that but i can only get about 4 feet of air i have a high pole would fatsacs or a tower make that much of a difference

The sacks kick ass, we put 1440lbs of water in our boat and it throws massive wake. Then if that isnt enough try some double ups. Timing is everything on them but man you will get super air. 70 feet of rope helps but more speed is required. As far as a tower we have a zero flex and it seems a bit taller than others Ive been around so ofcourse that would help too

fat sacs will make a huge difference I have malibu sportster that has a great ski wake, but when I fill up the two 550lb fat sacks and put the wedge down it makes a 3 ft tall ramp of a wake
