check out the bowhunting forum - go to page 11 - then click on interesting video and watch it. it's a test between limbsaver and bowjax. bowjax definitely has alot more vibration and noise reduction. i have always used limbsaver and it does a good job, but after seeing that video i'm going to give bowjax a try. also with the speed of cb's nowadays, the bolt seems to get to the deer before they react -for the most part, imo. and you usually will only get one shot at deer anyways. hope this helps!
