I've been having problems shooting any sort of a reasonable group. Generally I've been shooting to the left, and can occasionally put a couple arrows close together, but getting a presentable group hasn't happened. I've been assuming that I'm just a bad shot. The other day I decided to adjust the sight to try to get my arrows moved right. I moved the sight as far as I could and still shooting left. Upon closer inspection, it looks like the fletching is hitting the rest? So what would you recommend? I don't know if changing the brushes on the octane would be enough? I've also though about just changing out the rest altogether. If so what do you recommend? I've looked at everything from a Whisker Biscuit to a QAD HDX, plus a few in between. What would be best? Look for the wear lines between the left and bottom brush.
