RE: Shaft weight difference?
OK, assuming they are both the same spine #, you are probably OK, but I would`nt try any fancy shooting past 30yds. Your best bet, if you can not get all the same arrows, is to try both types at longer distance, and see how they work for you. I have tried beman ICS field arrows, and ICS hunters. They are 2 grains per inch different. Shooting a 29" arrow, they are not compatible past 20 yds, but that is a 58 grain difference.
