I got a chance to shot the stinger this weekend and first impressions of the bow was I liked the grip much better than my Patriot but it was just to light for my taste, I like for a bow to weigh around 4lbs bare bow. just my own preferance. When I shot it I thought D@mn I am holding a jackhammer in my hand, it had so much vibration my teeth didn't stop chantering for 10 mins. I think you could tame it some with limb savers and stabilizer. It had string silencers and a nock. When I shot it, it sounded loud but when someone else shot it the noise not as bad from a distance or 5 feet. I have not shot the Tech29 but my brothers Mighty Mite is faster, not as noisy, and does not have near as much Vibration, but the MM has a little more kick on the shot than the stinger. The stinger was a 60lb model max out to 61lbs and the MM was a 70lb model set on 63lbs. I hope the shop get some more of there bows in so I can shot them but I will bet the Patriot DC will be in my arsenal next spring.
