My Pheonix loves Easton Power Bolts. Under $5 bucks a pop. I think they weighed in at 321gr. without a head which will be 100gr. I am sure they shoot better than I do so I'm just fine. Sure not afraid of a 30 yard shot but that would be pretty much it regardless of the arrow.
I think there must be better arrows out thereand I would get them in a minute IF I thought they would improve my accuracy. It's like my rifles I guess. The guns might shoot 1 inch 100 yard groups but I never will.
