I havent used carbon arrows much so my knowledge of them is limited, I've always used alumin, but in my phoenix I'm shooting beman thunderbolts with 4" feathers set at a 5 deg offset, theaded inserts for nocks and 125gr points(NAP thunderhead broadheads) I went with 125 gr points and threaded inserts instead of solid nocks to get the FOC balance a little better, even though it turned out that the beman/easton threaded inserts actually weight slightly more than the solid nocks they use I still needed the threaded inserts for my fletchingjig, the FOCstill ended up being around 12%, which isnt bad, and I ended up with an arrow weight of around 438gr

as isthey shoot great out of my bow, no in-flight goofiness, straight line impact on the target, and good groupings



I also have a set of alumin 2216's set up the same way as my carbons, just in case I decide I dont care for the carbon arrows and want to switch,set up like they are they weigh around 438gr also(almost the exact same weight as the carbons)with a FOC of around 11% so there isnt much difference between the two, in fact they both perform pretty much exactly the same, and equally well, butfor now I think I'm going to stick with the carbons and see how they work out
