I'm curious, since I've been thinking of trying one out on my compound, what makes one of these better than another? They look so similar. A rod with a rubber cushion on the end. I also have read that getting the gap between it and the string adjusted properly is important. If the product has no adjustment (as it appears to be in the rear mount model), how can it be considered the best? For me, there's no way I'm screwing around with my bow's brace height or draw length to to accomodate a noise suppressor.

So, does this rear mount have an adjustment I can't see, or doesn't it matter if it's in an exact position?
