I think you'll just have to experiment and see if you're more accurate with more weight on your index finger, more weight on your ring finger, or weight more evenly distributed among the three fingers. Accuracy is the most important thing, of course, but aside from that:
-The bow will be quieter as the point of pull is shifted toward the nock
-The nock point will be lower as the point of pull is shifted toward the nock.
I was just looking at a fairly new glove I've been using, and the hide is being worn off on the pad of my middle finger, and hardly any wear on either of the other two fingers. That doesn't surprise me, because I also have a callus on the pad of my middle finger, even though I always wear a glove. Now whether that's good, bad, or indifferent, I can't tell you.
