Well, ever since getting rid of my training wheels and picking up a Trad bow many years ago, my two longbows have never ever shot anything other than wooden shafts.
My 55lb Blackwidow PLX shoots really well with 70-75# Surewoods and 160 grains up front, and my 75lb PLX absolutely loves 105-110# Surewoods with 235 grains or 135# Forrester Wood Shafts with 335 grains out on the sharp end.
Wooden arrows still seem to put all sorts and sizes of game on the ground without any fuss. I've taken game from rabbits to buffalo with wooden arrows, and plenty of other things in between. I really don't see any reason to change.
Is wood as straight and as consistent as carbon or aluminium? Not as a rule. But with a little care they can be more than straight and consistent enough.
And I love settling down to start making up another set of wooden arrows. I find it very therapeutic after a tough week at work.
Best
