I have owned 3 Mathews bows and now my Bowtech 82nd Airborne which have the roller guide instead of the cable slide. What I have noticed is that when they are tuned in and shooting good that my sight, string, and arrow don't line up. If I look at the bow from behind the arrow is considerably to the left of center. I noticed it the other day on my brothers Switchback also. I looked at my Bowtech Commander which has a cable slide and everything is perfectly in line. Anyone else ever notice this? I was speaking to a Hoyt rep. this past spring and he pointed it out but I didn't pay too much attention to it until recently. He said that it is a common on roller guide bows, but if he said why I guess I wasn't listening. He said that if Hoyt goes to a roller guide bow that he would give up on Hoyts. Guess he wasn't too impressed with it. Not sure why. Anyone have any answers?
