I use the no-pulse set up on two Turner biothanes and a Weller leather for SR. Do a Google and you will come up with how to rig it. It is convenient to have it on your arm when you go to the line, and just have to string it. Also its easier to adjust if you need to take up a notch. There is one problem, the keeper wants to walk into the frog. I solved that by a pop rivet so the keeper doesn't walk. Dont do it right away, get familiar with it and you will see what I'm talking about. I see a lot of shooters using this configuration now. I don't think it has any effect on pulse though, just easier to sling up and adjust.
A trick to getting the biothane to release... grab where the end is attached to the frog, and give a tug up and back.
I put a web sling on (parade) for off-hand.
