My preferred arrow build is a bit more than what you're looking for.
GT hunter xt 300
100 gr brass insert
125 gr head
4x 75/105 gateway rayzr feathers
Cut 28" carbon to carbon.
20 % foc, 510-ish total arrow weight, stabilizes right now out of the bow, and tunes so very nicely. Yes, it's over spined for my 63 pound Anarchy SC, but that bow loves a heavy stiff arrow.
