I was doing some practice with a tru ball chappy boss release today. I could not get a idea of weather it was going to tighten up my groups or not. For me to really tell I need to lenghten my draw lenght an inch so I got a good nocking point. The release is my shop owners back up and is slightly used and I can buy it for 50 dollars. He taught me how to use it as a back tension release.

What should I do, buy it and raise my draw length just to see if I like it and my groups will tighten up or not.

Right now I am shooting a 15 year old high country wrist strap caliper release.
