Ah, the light bulb just turned on!! I was typing a response but just deleted the whole thing. Starting over now. In regards to moving the sheet point fore and aft, we're talking about jib twist. I need that twist to match the amount in the main. So if my main has little twist, and the jib is sheeted back further (causing more twist) that would make my upper tales break early and blow forward.

Two questions more then.
So by having the jib sheet point too far out compared to where my main is, I loosing air flow over the main sail and effectively loosing power? Correct?

Would this setup cause me to have more weather helm?
