arrow spine

375 4
I just bought a pse xforce 7 and need some hunting/target arrows , I have asked a couple sales people and they are recomending quite a bit lighter spine than the chart is saying. I need 30.5" arrows {I draw 30"} and the bow is at 74 lbs with fairly radical this ok and any recomendations?

5g per #60 - 300g, #70 - 350g...the heavier the arrow the more kenetic energy you will have down range, but you will lose speed. You need to pick and adjust...see what works good out of the bow...but don't under spine...
