BigC--I traded a Zipper Extreme for another t/d recurve and I just couldn't group with that bow to save my life.No matter what I did or what arrows I used--I just could not shoot it.I got the bow on a Monday and traded it off that Friday.The guy that took it off my hands was stacking the arrows in like he'd been shooting that bow his whole life.Thankfully I haven't come across many bows like that.I sure do miss that Zipper,though!
