Re: Genoa tracks
Lead position controls twist. It will not move the draft.
Where the leads should be really depends on your particular sails. A good rule of thumb for upwind trim is to use upper, middle, and lower telltales. with the sail trimmed for close hauled, all 3 sets of telltales should be streaming. Slowly pinch up higher, and all 3 telltales should start to "break" at about the same time. If the top starts to break first, the lead probably needs to go forward a bit.
When you crack off onto a reach, you will probably want to move the car forward to maintain leech tension as the sheet is eased.
When you are starting to get over powered, move the cars aft to open up the leech, (increased twist) to "spill" some power from the upper part of the sail. Combine that with increased sheet tension to flatten the rest of the sail. (Increased twist is also desireable in very light wind conditions.)
