Specs:
Diamond Outlaw 2011
30.5" Draw length
65# Draw wieght
Hostage arrow rest
Arrows
Carbon Fury 4560 (100gr per inch)
28.25" Length
NAP Twister Quick FLetch
Nockturnal nocks

So, when I shoot stock vaned arrow with 100gr FT I am dead on 40yds and in.

The problem is when I shoot practice BH (Grimreaper 3 blade mechanical) and NAP Twister vanes. My arrow is consistently 3" left and 5-6" high. 2 blade practice Rage BH's are dead on with the NAP twister, but not the grim reaper. Not sure what is going on.

Another issue is the looping motion the arrow makes which is easier to see when I shoot the lighted nocks. Not sure what to do about that.

Can you guys help? I would greatly appreciate any advice,

Thanks
