Good Arrows are the most important factor in Archery from my point of view. Although I shoot traditional type bows and use home made wooden arrows, good aluminium shafts will be more accurate and consistent than wooden ones. I shoot in some tight bush and on the rare occasions I miss
my shafts tend to hit/ricochet off branches etc. Wooden shafts tend to "bend" around branches, where alloy shafts would take a set. If I was in more "open" country I would definately use Alloy or carbon as without a doubt they are far superior shafts.
I have tried to straighten Alloy shafts but they have never quite been the same afterwards. I have tried to get the raw unfinished Alloy shafts from metal suppliers but no one stocks them, it seems they are made specifically for Easton etc.
