One more thing that I forgot to mention is that the paint on arrows can make them hard to get out of targets. I bought some camo painted Easton Axis and they flew just fine and were a little heavier (depending on your application this can be good - I hunted with them and didn't mind that they were a few feet per second slower because I figured that it more than made up for it in kinetic energy). They flew straight and performed well, so no complaints from that standpoint. HOWEVER, the problem that I had was getting them back out of the target. Even putting the arrow lube on their didn't help all that much. At some of the 3d shoots with cheaper targets it took two of us to get them back out - not as much of an issue on high-quality targets, though. But for that reason I usually just stick to the plain, unpainted arrows now.
I love my Easton FMJ's I have heard people talk about them bending because of the metal jacket but I have had no problems.But when you ask such a broad question your going to get alot of different answers Its like saying whats the best rifle or best diesel or best set of boobs. In the long run you come to find what ever of the above stated you can get your hands on will make you smile
