Buckeye, I have seen what an STS can do for a bow and don't doubt for one minute that it could really quiet the Drenalin down. I am just reporting on how the bows come from the factory with minimal additions. This is just my honest opinion and take it for what it's worth. I think I did state somewhere that the Drenalin could be quieted down and vibration reduced. Not sure if it was on this thread or some other one somewhere. Now as for the 2007 Bowtech Allegiance and the Gardian and Commander I am really anxious to get my hands on these bows and put them through their paces. Gotta love new bow season!
