Well, I've been working with carbons now for about a year and have tried and tried to get the CX 350's and GT 7595's to shoot well. I went with the recommendation of a CX arrow technician instead of you guys and won't do that again!
So, I bought a batch of fletched CX250's from a Trad-ganger here to try and LOVE the results!!! Kept them 29" long and still using 250 gr. up front. They weigh roughly 600 gr. total and I can't believe the difference in arrow flight! They just seem so much more stable and straight.
Pics are of a target in my back yard where I shot a group at roughly 20 yds. check it out:

You'll have to excuse all the wild holes in that target---I was VERY new to this just 2 years ago--from shooting a X-bow---took ALOT of shots to get me where I want to be---still not there yet either!
