John,

I have used the dual nockset with the bottom one being longer for quite a while on everything from nitrous cams, to single cams, to binaries. I really like this best because it can put just a bit of down pressure on the arrow to keep it planted on the blade (target applications), and it keeps the release inline with the arrow. I really hate nock pinch, and have seen some drastic arrow flight problems caused by it.

I do think this year that on whatever bow I will be shooting for indoors season I will probably try a release rope again and no loop. There are some significant advantages to this on a target specific rig using a sear style thumb trigger or hinge.
