I just put azero effect next generation on my hoyt razortec. It was a breeze to set up and adjust. Be sure to get the correct model for your particular bow, i.e. hoyt tec model, mathews model, or parallel limb model. For more specifics on the rest, search this forum for the review that was done on the zero effect by Greg / MO. It really explains how good the rest is. By the way, they are super cheap at http://shop.eaglearchery.com/browse.cfm/2,396.html($50 - $55) and they only charge $2.00 for shipping.
