i shoot 52lbs. @27" draw.i use the cx 150 heritages,cut 29.5 to throat,wrap,4 5" gateways,and 175grns. worth of magnus 2 blade up front and these arrows fly awesome.bare shaft tune,broadhead tune,what ever.my opinion is the cx's are a better arrow than gold tips.if you weight each arrow from a dozen of cx's and a dozen of goldtips you will see right away the gold tips have a larger spread from arrow to arrow and we've found the cx's to be a bit more durable.i like the concept of the skinning easton axis shafts,i just don't like the ****,i'm sorry,hit technology.putting the broadhead or point right against the weekest part of the carbon arrow(un protected end) is STUUUUUUPID.if they would come out with a better insert and get rid of the one you have to enbed down the shaft,they might have something.beware of gimmicks like frequency dampners on them as well.good luck in your arrow adventures and one vote here for the cx heritages,good arrows.
