What are your thoughts relative to the D loop being tied under the arrow nock as opposed to "splitting the nock", that is one knot above the nock and one below? I know downward pressure on the arrow rest is a factor, but is there an advantage, disadvantage for one over the other? I have tried both and prefer the loop under the arrow nock. I can not determine if there is an appreciable difference (arrow flight, grouping etc.) between the two, but then, I am not that knowledgeable in this area. I shoot a Carter Solution 3 (back tension) release.
