So I stand pretty far out, usually where the whitewash meets the smooth water.
Looking out ahead on the left side of the boat I use the left pre gate and 1 ball, when they intersect I pull out. (36mph)
I learned that from Ian Trapp when he coached me way back in the day, and I liked it because its very very consistent.
When I turn in I'm looking at the gates, but I shift my eyes to 1 ball when I hit the whitewash.
For every line length shorter I pull out a tad later; as a visual probably half an inch. I do that to be able to get to that wide spot every time since the line will want to pull you back in as it gets shorter. That way you're never changing how hard you pull out that stays the same always. You're just changing WHEN you pull out.
Hope this helps!
