RE: Do string loops slow your string??
I would think changing your anchor point would be more of a concern to me. If I was to take mine off I would add a half of an inch to my draw length and shorten 1/2 inch if I added one. I do belive you may lose only a few feet per second. But I would think you should still go with your natural anchor point. If it don't make you draw to far you may be ok, but ruin your form, this could hurt you rather than help you.
