Thanks for the info guys. My draw length is 29". I based the arrow spine according to selection charts. I was curious about the tip weight but that's what was recommended from the shop I bought my original arrows from. At the time I was using a 66lb draw weight. The Parker I have now is set at the low end because I'm switching from a rh to a lh bow and my left arm is the weaker of the two. I throw righty but I'm left eye dominant. The switch was because I knew it would be harder to switch later when bad habits have already set in. The draw will be increased to around 65lbs because I know keeping the bow at the bottom end isn't taking advantage of it's full potential. I have no intention of going to 70lbs as I don't think it's necessary to hunt deer and turkey.

Mentioning broadheads, my grouping was better with the BHs than it has been with fieldpoints. Seems strange, but the BHs grouped within 4" at about 24yds. The fieldpoints grouped wider, sometimes 6" or more, and always seemed to have at least one errant shot.
