Been shooting beman ics for 3 years now....while they are very durable, straightness is a problem, but until last year I had no problem. I bought a dozen of new bemans and was trying to paper test my bow....It was just not happening....I spin checked the arrows and out of that new dozen, there were 5 arrows that were, what i consider good enough to hunt with. so i put by 100 gr Muzzys on the good 5. After a few shots with them they started flying crazy, so i took off the broadheads and spin checked the "good 5" again, and after shooting just a few times, the "good 5", were just as bad as the rest of the dozen. So after last year, needless to say I will be switching back to my trusty xx78 Super Slams.
