Ken, just an opinion here but for broadhead arrows I believe that a straight shaft is fine, about 11/32 poc is what I normaly use with a 100 grain point, slightly less foc seems to help carry a bit further. Are you thinking about attending the flight shoots at some point, I have a feeling you would enjoy it, just the people who attend make the trip worthwhile. I think the 7,000 ft elevation may aslo give the distance a little boost. I was shooting a modern longbow at sea level that was measured to be about the fastest any longbow has ever shot and was only getting about 215 yards. Steve
