Thanks Arthur P....

My XX75's are cut to 30.5" and with a 125gr tip, the whole kit 'n kaboodle weighs in at 568 grains. (flying tire iron! )

I was thinking that a 5" feather would have a touch more weight than a 4" feather and would help out better. To be quite honest, I have never shot a feathered arrow before, and have no clue what to expect. I just use the common basic 2315 cut to 30.5" with the regular Easton 4" vanes.
