Hi Mike, sounded like a Niagara, I used to own hull #1, had great fun with it. What you are seeing would not correctly be described as luffing it sounds like a light air version of the fluttering you get on the leech of a jib when you do not have enough tension. Perhaps the stiffness of the kevlar caused a larger section of the leech to move or oscilate.
I do not think it is a big deal, a small amount of tension would likely eliminate it.
I would not move out to the rail. In light air you generally put a little twist in the genoa by moving the car back one. However you may find that the wind up higher is a bit stronger and therefore more forward so then you would not twist it, perhaps even go the other way.
