Just keep in mind that IBO specs are always obtained with a 350-grain arrow (for 70-lb. bows, to achieve the 5-grain-per-lb. recommended minimum) at 30 inches... anything that takes away from that will rob you of the stated IBO speed...

If you want to be in the 315's with a hunting-weight arrow shooting at 29 1/2", I'd suggest looking at the Airborne 82

But here's the reality of it all: If you'd never shot through a chrono, you'd probably never be able to tell if your bow was hitting 298 or 310. The naked eye can't distinguish the two; it's more of a "macho" thing.

Remember this... Matt / PA and I were talking on the phone last night as I was coming out of a new spot I'd hunted for the first time, and we were chatting about the new '08 lineup Bowtech has put out this year. We were both getting excited about shooting a 450-grain arrow out of our new Airborne 82nds and talking about the outrageous speeds and KE we'll be getting out of them, when Matt brought us both back down to earth with a dose of cold, hard reality. He said, "Yeah, but I just killed the biggest buck of my life with an arrow that was going 145! And it slammed all the way through him!"

Yep, hard to argue with that!
