Brad--I taught myself with stock ballast (Pro-V) and only a driver and flag holder. Ballast was full, and passenger in the back corner. Three arm spans of ski rope from the tower, and 10 feet of lake depth. Sounds like you're 600lbs better off than I was...I would start tomorrow! If you learn on a small wake, the BIG ones will be gravy!
Ideally, Larry's post is right though, especially about NOT coiling the rope. And the link is great!!
