I'm looking for someone with "ontarget2", to run some numbers forme. I'm looking at buying, "Carbon Express terminator select xp" arrows. If someone could check to see what arrow spine I wouldneed I would be very grateful.

I have a"Parker Ultra Lite 31", (I think its a 2005 model, I'm not sure)

The arrows that I'm currentlyshooting are cut to28.5"

My bow is set at 71 lbs. (Maxed out)


Also, I'm shooting 100 grain broadheads/field points. I'm not sure if thats the correct weight for these new arrows. Please let me know if I should get heavier or lighter arrow tips. Thanks.

Let me know if you need more info. Thanks again!
