You can try a yoyo line (like on a Fury) to see if your first guess is in about the right place before making holes in the kite
Ian, I'm not familiar with the fury, do you have a picture (or a link to one?).
I should add that the kite in question (that previously did not have yoyo stoppers) had holes in the leading edge where they belong... so my quest is currently on hold. That being said, I do see the need for this knowledge if future builds so will keep exploring ideas.
