I have 2 of 'em, both on 3 piece recurves, a Predator and a BW SA, both attached with riser insert bolts. Rock solid, and the quivers are too!! John Dill is a stand-up guy.
Had a couple strap-on quivers in the past,(great northern and a boa, I believe), and wasn't impressed. Now, Kanati's are probably better, but I prefer bolt-ons.JMO
I'm thinking any quiver is going to affect "performance" on most bows, you just have to tune your bow and arrows with the quiver attached.
Is it mechanically durable? (Are snaps/knobs/stitchings, etc. holding up?)
I know from experience that any issues with the Kanati will be quickly and professionally dealt with by John himself, even if it means he has to pull over and take notes!
