Loon and DC, yeah contact toward the back made sense to me too. I never considered that belly contact would change the arrow angle, that's a great thing to consider. I can't remember where, but I was looking at a blog or buildalong and they removed wood on the 'backside' of the bow with the idea that the arrow would recover from paradox sooner if it had good clearance past the riser. I guess if the angle was good before doing this it makes sense, but on a narrow handle you might be cutting into the back to far.
Peacebow, so would you say, other than getting clean arrow flight, that tuning the arrow pass is a part of tuning your arrows? Would moving the point of contact forward or back be a way of clearing up minor spine issues?
