RE: Changing Arrows
Your OVERSPINED and A LOT!!! With your set-up, even shooting that longer arrow, you need a 500-550 spine to be optimal. IF you arrow isn't spined close, it's won't fly well. To get the "perfect spine" you need to step up to a 510 FMJ, and put a 125gr tip on there. Gold tip doesn't even make anything that hits the right spine for you set-up according to OT2.
These arrows should work for you.....
PSE RadialXPRO .520 spine
Easton arrows in a .510 or .520 spine
Beman ICS Energy in a .520
Blackhawks in .490 -.505 would be just a little overspined.
