RE: is anyone still faithful so aluminum arrows?
Regarding straightness, carbon arrows offer a distinct benefit over aluminums. While a carbon arrow's advertised specs may be no straighter than a typical aluminum shaft, carbon arrows resist distorting and "bending out of shape" much better than aluminum arrows. Though an aluminum shaft may BEGIN with a similar ±.003" straightness, it's straightness quickly deteriorates through normal use and handling. So after a few months of use, your aluminum arrow set may contain a few arrows that are ±.003", a few at ±.012", and a few at ±.025". Carbon arrows generally do not retain this kind of "memory" after being stressed. So your carbon arrow set stays much more straight and uniform - even with heavy use. Some archers even joke that there are only two states of a carbon arrow: straight or broken, but never bent. While that's not entirely accurate, it does help to illustrate the point.
