"I own a Quinn Stallion Classic and a regular Stallion as a backup. I don't believe you'll have any worries where longevity is concerned, they're quality products. The riser is made of aluminum, so it isn't going to rust. The limbs are well-made and I believe that as long as you take care of them (no dry fires, etc) they will last a long time.
Until I got a Toelke Whip late last year, my Classic was my primary bow and I must admit I subjected that poor thing to everything imagineable on numerous hunts. I'm talking 90+ degree Texas weather for hours at a time, getting drenched in a flash storm, scuffed up on rocks while crawling on the ground, numerous bouncing rides in the back of trucks/jeeps, a semi-dry fire by my brother-in-law (nock slipped off the string partway through his shot, I almost feinted and haven't let anyone touch that bow since, heh). Anyway, through all of this, that bow has held up -- has the scars to show it, but it's been a trusted 'hunting buddy' through thick and thin. I actually feel guilty taking my Whip (which used still cost 2x more than a brand new Classic would) on hunts and leaving the Classic behind, if that says anything"
Thanks for taking the time to share that. That's just the kind of stuff I was hoping to hear. With everything I've heard about the Quinn bows, I can't say I was all that surprised but it is always nice to hear/read more.
