The Quinn bows have thin cork on the riser limb pads. For hunting you have to quiet them down like any other recurve, and less than 9 gpp is usually noisy like any other recurve. I've never used limbsavers, but always use string slap padding on all my recurves.
If you're going to shoot off-shelf (Stallion is best for that), you have to build the sideplate out considerably... they are cut 5/16" past center. For the flat shelf models (Stingray and Comet XL), the NAP Centerrest or the Bear Weatherrest are good choices.
Limb performance is better than average and draw force curve is consistent through 29". Like most recurves, increase per inch is more between 29-31", but not even close to what would be considered "stacking".
