elkken,
You may be right on the draw weight. I think this bow just likes a stiff arrow. Id be hesitant to go too much heavier on point weight, and the arrow is at 29", I don't really want to go much shorter. I did kindof a combo tuning exercise...bareshaft and broadhead tuned. I bareshafted a single fmj 400, and it liked what it liked. standard insert and around 150 gr head. Then I broadhead tuned another arrow. Again, apx 150 head was pretty perfect. I varied my point weights from 100 gr to 300 gr with the aluminum and brass inserts (both with field points on the bareshaft and broadheads on the fletched). That way I could see the arrow fly weak....then straight...then stiff... Then of course I went back to the best flying combo. And the big ol zwickey delta's are flying god to 35 yards. Haven't tried my old sasquatch's yet, but I don't intend to use them hunting.
Also the arrows that RMSG set me up with were 29" carbon express heritage 250's (also about a .400 spine if I recall), with 150 gr points. So it definitely likes the 400's with about 150 gr point. The 340's will be here soon. I'll probably load up the brass inserts and repeat my tuning process. Hopefully end up with an apx 600 grain arrow.
TexasKing,
I did join the IBA. I might just go out there tomorrow night and shoot the little 3d course.
