I did it with a mathews a few years ago at a local shop. I shot either a SQ2 or a MQ32 and it was completely dead in my hand. No forward movement at all. Then I asked to shoot one of the faster bows, an Ultra 2 I think. I asked if it was just as shock free as the other one and he said sure. Well it shot right of my hand and he grabbed it after the first bounce. I just looked at him and said " That was nothing like the other bow!, sorry." He just said I had nice follow thru and that if I get that bow I should get a wrist sling, and winked at me. I thought I was going to have to pay for it or something.
I now hold on to any bow I shoot that isn't mine. It is actually a good way to see how much vibration they have after the shot. I close my eyes sometimes as well. ( the shop I go to has the target like 2 feet infront of you, missing is not really an option
