You mentioned custom arrows, a good arrow maker should be able to get you set up just right.
You also may want to tell us your exact setup bow poundage at bows draw length, your actual draw length, what type of string and how many strands, center shot measurement and I'll be happy to check it out on Stu's for you. I'm guessing that you have never used Stu's since your asking and I highly recommend not using it on your first set of arrows if you're not familiar with it. I've had very good luck with Stu's but it was a little tricky before I figured it out.
