Need help with a mathews switchback. I kept shooting to the left so I moved my rest and my sight and they are both maxed out and I am hitting where in aiming now but my arrow is flying wierd! I'm pulling 60 lbs and my arrows are 45-60lbs do I need stiffer arrows?
Start over. Set your rest at 3/4" from the riser and set nock point 1/16" high of 90 degrees. This is a good starting point. Shoot through paper and see what kind of tear you are getting and make slight adjustments to the nock point and/or rest. Also, check idler lean. Hard to get a good tear with excessive idler lean. When you get a good tear through paper, walk back and then broadhead tune. The Switchback was one of the easiest bows to tune that I've ever worked on. SCFox
I went through something like that. Finally at my third bow shop, they figured out my cams were out of sync. It's kosher now but before it changed all the time. Paper tuning was useless and a waste of time.
