I've shot many bows and have been fortunate enough to. I really didn't care for the Vipertec to much. I owned a Legacy which was quiet, but fell for this cam and 1/2 craze. I shot a couple of these Bowtech bows and liked them a lot more then the Hoyt bows, and I liked it a lot better then the Outback that I shot. I'm not really looking to get rid of the Hoyt just for the sound. I personally don't think that the bare Bowtech bows, without the hush kit is nearly as loud as the Vipertec without the leeches. The Vipertec with the leeches on was a lot louder then my buddys Mathews Lx. I shot a copule of these Bowtechs, and more then a couple Mathews guys had told me that the Bowtechs are the quietest they've heard!
