Weird. I had the same problem with my 06 Ally:

I bought an 82nd and it was a breeze to tune. Paper, walk-back, broadhead all good. I loved the Ally but the 82nd is more accurate and 60 lbs is a dream.I am shooting 27.5" mods with 5575 GT Pro Huntersand a Trophy Taker.

TFOX ran the spine it was close tobeing weak - but OK - so I stayed with 5575's because I have more of them. I have some 7595's thatpaper tuned great so Irecommend going to a stiffer (.340) arrow.
