good cedars are hard to find. Well, not hard, but expensive. I use cedars with my selfbows and backed bows. I use alums for my fiberglass backed recurves and longbows.
Most selfbows, you have to go down to 1816s and are fragile to say the least for a 50lbs selfbow with a 1/8 inch or more offset. Cedars are dead quiet.
I went down the carbon road, they are tough, and work great for heavier longbows, but so much work to get good weight and proper spine. After messing with all the inserts, and getting an arrow combo that works, it got to the point that I could buy alums and be done with it.
