PABeardBuster- Yes I have to give credit were credit is due the Hoyt Razortec is simply awesome. But I do think that the NAP Quicktune 4000 has a lot to do with it. Until I shot this combination I would not even have thought about shooting at a deer past 30 yards. However with this combination I am extremely confident out to 40yards. I purchased the razortech this summer and set it up myself. I went out and shot my first arrow and immediately had perfect arrow flight. I adjusted my pin (I use a single pin) one time and I have not had to adjust the first thing on this bow since. It was almost to good to be true. I am shooting a 405 grain CX arrow with a 30" draw at 65#' s and getting 280fps with a KE 70#' s. I like my Razortec!!!
