The best thing to do is go to a pro shop that has someone with some knowledge on trad bows. Then draw the bow and get your draw length measured because it will be different than what it is shooting a compound generally shorter. When it comes to arrows I would get a few different sizes and start shooting them at full length and cut off like a 1/4" at a time until they are grouping well. Once you find the arrow that groups the best I would bare shaft to see if they still group with the fletched ones that way you know for sure you got the best shooting arrows. As far as arrow weight 500+grains is my preference. Good luck.
