RE: Anything I should know about these shafts?
Good alum shaft. Just make sure you check the Easton catalog for detailed specs. weight tolerances may be a bit looser, as well as the the shaft strength compared to " standard XX75 (like the Shafts Frank mentioned are)
BTW. ' 04 Easton website is up. Some cool new stuff.
P.S. With your current bow set-up RB, 3-60' s w/ 125 grain points should spine just fine and will get a bit higher in weight (around 425 grains or so)
