Like an idiot, no I didn't put marks on my cam. However, I have installed a no peep, and the bow doesn't really feel like it's drawing longer, and the no-peep is still right on the money.
The string and cables are #8125. The only things that have changed from shooting good to not shooting good, which seemed to take place overnight, is I installed a set of SVL leeches and had my arrows refletched, but with the same size feathers, 4" parabolic.
I can't say the leeches are doing much for me, as my bow was whisper quiet to begin with, but I bought them on clearance last winter and was curious. I think I'll take them off (they've lasted about 30 shots by the way

), and start my tune job from scratch.
I don't know what the heck happened, but I'm perplexed. Last week I was shooting the tightest groups ever, now I'm having trouble holding 4" at 20 yards. I'm lost.
