Don't have any prefernce and all shafts have their place around my house.
Only used carbons for about eight years now, but like how they last after errant shots and how light the shaft is for some low draw weight bows I have on my rack. Have a bunch of inexpensive Predator II's with 3.5-inch feathers and the leading edge of those feathers are twine wrapped. They fly great with some good weight up front with all my mid 40lb'er bows. After I tried Axis Trad 600's with those bows, liked them even better with the smooth outside finish. Use brass inserts with them and they shoot fantastic. Always keep at least a half dozen shafts for fletching in addition to 15 to 18 othes ready to go. Use Onestringer fancy wraps with them and as I have always done the past 50 years, fletch with two reds and a yellow for good luck. Same colors my instructor had fletched when he gave my my first aluminums at a regional field archery event in '62.
However, I too will be buying some aluminums for my favorite bow I will be shooting at 3-D and other archery events. A 1962 38lb Brazilian rosewood recurve, think some good ole 1714 X-7's shot off a feather rest will bring up my enjoyment of that bow just up one more notch. Got plenty of hunting bows so need some good aluminums for my favorite everyday bow. Might make some woodies too later this year if I need them. To me, they've always been work horse hunting arrows, which I used to solid dip and go small game hunting with. Not into woodie art, but really enjoy looking at the arrow art work of others.
