A couple weeks ago I was at a 3D shoot and as I drew my Pantera I could feel that there was a drag somewhere. I looked everything over pretty much after everyshot from that point on and didnt find anything wrong. After I got home I worked with it for about an hour , I took the OEM slide off and noticed that the side that was in contact with the rod was starting to show signs of galding. I was surprised at this becuase I use teflon spray and I rub all this down at least once per week. Anyway, I had a couple limbsaver slides down in my shop so I replaced the bad one and went ahead and replaced the one on my Onza as well. That took care of the problem.
look @ the Sanders Hyper Slide, have them on all my bows and they realy work well. Have read that the Hyper will add a few fps.
My rod does Show signs of wear im gona turn it and see if it helps.
