I currently own 3 Zippers. A standard riser,a SXT, and a ZSR. The Standard 60",was my first and a real plain jane, but sooo smooth and quiet. I kept it and now have it carbon film dipped and use it for bowfishing. I could take the bowfishing gear off today and be very happy with how it shoots. The SXT 60", has Evolution limbs with carbon/foam. Again, beautiful bow, smooth, quiet and fast. My favorite off all is my ZSR 58" with Evolution limbs and the Accelerator limb wedges. Prettiest of the 3 and a more custom grip. A new Zipper "Hunter" model must be about as good as it gets for a few less bucks! Plus, and not to be understated, Bill and Tracy are the finest peple to deal with.
