A C&P from AT
I'm not sure anyone is "best". They all have good and bad points
CX/PSE: Tight spine, tight weight, straightness is better in their mid grade shafts than most. Durability is :yawn: (barring the Terminators which are very tough)
GoldTip: spine is not so tight, weight is tight, straightness in anything but the Pro series is a gamble. Very tough arrows.
Beman: Spine is tight, weights are tight..straightness is totally hit or miss. Fairly tough.
Easton: basically the same as Beman (same construction types/company), but straightness is usually a little better on average, but still poor a large percentage of the time.
I'd like to get some Carbon-Techs for testing, as well as some of the Phantom Pros.
If you want absolute precision, A/C/Cs are the way to go..tight spine, tight weight, tight straightness. But they cost big bucks.
Whatever brand you go with, just make sure you buy the absolute highest grade shafts they offer. You will have a lot less headaches.
And I'm not even taking into account things like ID & OD tolerances, components, longevity of straightness or spine..
They all kind of suck in their own way, and they all excel in their own way.
I initially was very impressed with the ST AXIS for example...then the problems showed up and I went elsewhere for a bit...but because of the penetration, and how well they shoot (when they are straight), I may just end up full circle for hunting season. Some things about them suck, but sometimes the advantages outweight the disadvantages for the job at hand. In this case, I'm willing to buy a couple or three dozen and weed out the bad, and I won't be pounding them come hunting season, so It will be less likely I have issues to the same degree as when I was shooting them for couple hundred shots a week.
Carbon arrows have a ways to go yet...
