The draw cycle is smoother on the vectrix. The trykons cyclehad more of a valleyand made a little bump noise at full draw when the bow was peaked at 70 #. This was only noticeable on my high poundage bow and not on Hoytgirls lower poundage bow. I turned my trykon down to 64# at that took care of it though. If you are buying a 60# trykon you would never notice this probably; only a trait when the bow was peaked at 70#.My dealer noticed the same thing with his trykon and other customers'. The stealth shot STS type of sting noise suppressor that hoyt puton the vectrix has made the bows very quiet too. Onour trykons, I put cat whiskers on them and that made them whisper quiet. No need for whiskers on the vectrix. The new fuse string is suppossedly improved over last years string although our trykons strings performed flawlessly with the peep staying aligned. We use no rubber tubing on our peeps and the fuse string is a presretched ,no creep string. Both bows are very fast, quiet, accurate, and handshock free.
