For hunting never buy a velcro, too noisy! A single caliber release is more accurate than a dual, but I don't know if I would ever be able to tell. Scott makes some of the best, so does TruFire, Fletcher, and a few others. My best seller is the Scott Wildcat. If you have a shop close by you might want to go try a few if you can. Some like the glove style like the Tru Fire Hurricane or the Winn Free Flite. With those you need to know what size you want s,m,l,xl. If you want one in camo that is ok, but the little that is exposed will not make a difference and about $10.00 more.
