I don't personally have one but my brother and brother-in-law just had one installed and they both really like the strings. They both said that it solved there peep alignment problems. My brother order both cables and string for his Hoyt ViperTecand we think his cables run a little too long. When we checked his draw weight it was only 65lbs. on a 70lb. bow. We twisted the cables a couple of times and no good. So we are sending them back to have redone.
