Brantley's ATA Pick: Easton Injexion Arrow Shafts

We saw a ton of great new stuff at the 2012 ATA Show in Columbus, Ohio, but I'd have to say my favorite was this new A/C Injexion arrow shaft from Easton. I'm already hearing great things from pro-staffers who've had a chance to shoot it, both on the range and in the woods. Long and short, it allows you to use a heavy arrow with an ultra-small diameter. Those two characteristics, combined with a sharp broadhead and tuned bow, do wonders in improving penetration on game and flight charateristics, especially at long range. Check out this video and let me know what you think. Is it a cool idea, or does the limited broadhead availability too much of a drawback at this point?
