Okay, this one has me stumped:

'06 BowTech Old Glory, 71 lbs., 30", QAD HD drop away w/ 29" A/C Superslim 340, 125 gr. points and Blazer fletchings, Carter release and loop.

I set the arrow up just barely nock high at rest and notice that there is a bit of porpoise to the flight at 50 yards and that everything is shooting way high so I go to the paper. There is a nock low tear that takes me about 1/2" of raising the nock point to get rid of. This is the first bow I have ever had to set a nock point this high on to get rid of a nock low tear. Anyone have ideas what's causing this? Give me the list and hopefully you guys come up with something I haven't tried. My next resort is going to be flipping the limbs around (top to bottom).
