Honestly, not a lot of experience with carbon...I did (after shooting several different types of carbon)purchase a dozen of the toughest / straightest Carbon made "then" and likely still if they were still being made (without throwing the manufacture under the Bus
....but I have shot aluminum -fiberglass-wood since the late 60's . Mostly last 30+ yrs. I have "never" had an aluminum arrow break at the shot nor on impact. I have had many bend on impact or shortly after. With that matched dozen $$$ Carbon , I had one glance off a chainlink fence (as I have had MANY aluminums do over the years per
pre backstop days) That carbon snapped 1/3 back of the point as it went to flex around the wire it struck. Clean break. Though it matched my 2018 aluminum shaft setup near perfectly in weight and flight , that clean "break" had me selling them and never looking back. *Did any of my 2018 aluminum get damaged on that same fence? O yea...slight bends,NEVER a break. Breaks kinda creep me out ;^) So I'll take a shaft with the least likelyhood to Break every time.
For glancing blows like mentioned above , and to survive with the least damage....My vote would be a good wood shaft . ..followed by aluminum (though it may bend)...All this is very dependent upon material-gauge-wall thickness-etc....etc...
Kirk....I do bend some of my easton 2018's while stumping , or a critter might bend one that manages to "not" get a complete pass--through...but if that happens , more times than not I will hand straighten them and they are used for roving/small game shafts once they spin true.
Yes , the integrity of the original product has been forever compromised , hand straightened 2018's are plenty tough after a light bend to be straightened and utilized once again for lesser chores
Some of your lesser aluminum material or thinner walled aluminum....more than likely are toast after a bend. .....and even then they can be recycled into something useful ;^)
So that is the extent of "my experience-opinion" with carbon shafts...though I did my homework pre purchase to have the toughest-straightest-carbon shafts,and properly tuned to my rig..
Aluminum arrow shafts have treated me VERY WELL over a LOT of years. For me they are an excellent arrow shaft that has stood the test of time . They fill many an archers quivers, and many a hunters freezers and have so for a VERY long time. I have no cause to change that which is proven..You asked for our preference and why ...... You just got it ;^))
