I'm shooting a Tribute @70# and a 28 inch draw. My current arrows are 26" long and I'm shooting an 85 grain tip.

Which Maxima should I shoot? The carbon express arrow chart says 250? What is your opinion?

if your shooting 70 pounds i wouldnt shoot such a light combo. id go with a 300 and a 100 grain tip. the 250s are rated for 62 pound bows i believe

My Switchback XT is set at 65lbs. I'm using 100 grain heads, and using the 250s
