Stayed with aluminum; nothing derogitory with carbon
Always considered myself a part-time archer; full time gun hunter.
Even though I practiced a lot over the years, I was always satisfied with the slower bow and the slower arrow, if that were so.
I knew the back and forth of flething aluminum arrows; shot them accurate; used an inexpensive hacksaw to hand trim the lengths for practice and hunting.
And I'll admit, that cost for the expensive saws, made especially for carbon arrows, depleted any desire to shoot carbon arrows.
