OK, I read all these threads and posts on these topics and its driving me crazy! Can someone help because I'm lost. Here's my setup:

Buckmaster 2000 at 58lbs
27 1/2 inch 2213 Eastons w/ NAP Thunderheads 100 grn.
Timberline No Peep and trigger Release
Predator IV Pendulum sight.

My shop originally sold me 2213 Easton Aluminums and NAP Spitfire (now changed to 100 grn Thunderheads) with my bow and I've never changed arrow size. But as I look at the Easton Chart these arrows aren't even shown as acceptable now and I actually want to increase my bow's poundage a little for next year. All I do is bow hunt and just want a good arrow that will be accurate to my abiltiy (I can hit a tennis ball size target consistantly at 30 yards (my personal maximum) and that will produce the quickest kill with a good shot. I don't really care about the speed so long as it can do the job in the real hunting world.

From all I've read, I do not see any advantage for a person like me using Carbon arrows. So, Easton lists "light", "average", and "heavy-weight" sizes for aluminums all supposedly having the correct spine for my setup. How do I choose between the acceptable shafts listed in the Chart?

Sorry for the lenght of this post, but, I really need some help on understanding what I'm seeing. Thanks.
