I am going with the 100 gr heads, going to pick some up tonight to check the difference.
Definitely right eye dominant, been shooting for 27 yrs.
Paper tuning was perfect bullet hole, cable slide was at the 6 position, was checking cam lean so that's why it is a 3 postion. Really just max vs. min vane clearance, with plenty of discussion on Archery talk about this as fix to minor cam lean issues, to Jelly you don't necessarily want min. clearance on the cables.
I agree with the spine issue as the likely culprit, if that's not it, might be a manufacturing issue. That was also noted on this series of bows but I will be going with the low hanging fruit.
Also as a side note I shoot 29 1/2" 340's for my 70# Mathews and they shoot straight with everything broadhead and field point. But I have a little less on the front end by 34 grains. Aluminum vs brass insert. Kind of funny that 5#'s and 34 grains put me through the .300 spines. Also Easton's chart puts me right in the middle of 300 series or between .280 and .320 for arrows.
