Hi Greg, mostly use 32/34 there are a few that ski slower. Were not really turning all the way. The boat starts straight alongside an island, turns in around the front then straightens out before the pre-gates. Probably have 140 ft of straight run before the pregates once the boat is re-straightened. The software is the most recent version. One of the units is a week old. The buoy marker is a good idea, it was suggested by one of the guys that last time out, and will put it to work just to give us as much running room as possible. I'll see if google earth shows an aerial view.
