try the cheater 360's first.
Just as the boat is turning at the end of the lake to turn around; cut in heel side and the curl on the wake is more lippy. you will be boot a bit higher than a straight pass 360 (there is a small window to hit this, so make a couple turns to look for this lippy wake just as the boat turns) 2.) once fully in the air pull the handle into the small of your back very tight to your back "GRAB" the handle with your other hand you will come around with more slack than a straight pass 360 attempt but what this does is slow down the move and the speed (crashes are much more forgiving)This will get you familiar with the landings. you can do this for 5's 7's and so on........
Once comfortable on the turn 360's take it to the straight pass
