Has anyone been shooting these shafts yet? I want to switch to them, need information, I currently shoot a ACC-328 at 27 1/4 inches long, dura vanes 1.8 hyper speed points 70 grain. Total arrow weight is 315 grains getting 292 feet out of my '03 Hoyt Ultra-Tech at 5 grains per pound. Easton chart recommends the 400 shaft, I always feel that Easton recommends heavier shafts(AMO). Also my girlfriend is shooting ACC 3L-04 at 26 1/4 long same vanes and point weighing 285 grains 280 feet out of her Mathews Ultra II at 5 grains per pound any suggestions.
