While your gathering more information, you also need to know the draw wt of your bow at the draw length you're shooting. In general, there will be a 2-3#/inch decrease or increase when drawing shorter or longer than the usual 28", at which most, but not all bows are specified.
As a starting point for arrow selection, all of the manufacturers have 'spine' charts available on line and in their catalogs for helping in the initial selection process. Unfortunately, the carbon arrow charts don't seem to be nearly as accurate as the aluminum and woodie charts were/are; but they're a place to start.
Like many of us, you may find that the search for the illusive "perfect" carbon arrow may get a little expensive, so if the arrows you're using right now are flying well and grouping for you, stick with them. If not, once you've gathered the info needed to make an educated selection, come back with the info and I'm sure you'll get more different ideas than you'll be able to process!
But, that's part of the fun of Trad shooting, IMHO.
Have Fun!
