Doug,
Nice to see the good arrow flight your getting. I'm shooting Trad Heavies with 225 grains up front (100grain brass insert + 125 grain fp). have the arrows cut at 29.5 and am shooting out of ~60lb bow. Decided to strip the feathers off of a few to see how they were bareshafting. WOW! the bareshafts were hitting ~2ft to the left or showing very weak (at 15yds). Well after adjusting my centershot WAY out and reducing point weight I still couldn't get them to group. Soooooo I have concluded that they are WAY to STIFF and are bouncing off the riser (Dalaa)and showing a false weak. love the arrows but want to get the best arrow flight I can. Guess I'll try a few 200 - 250 grain fp's to see if they take out some of the spine.
