Watch a few videos. You find out that you don't need expensive carbon shafts. .001 straightness looks great. That's what aluminum shafts have also. 99% of bowhunters are not technically capable (myself included) of seeing accuracy differences between .001" and .003". Much more important to get them flying good and straight. 15-18% FOC is easy to obtain (but not with a heavy carbon shaft). Pick something in your spine requirement that is 8-9 grains per inch and add a 50gr insert. Make sure each end of the shaft is square. Squaring tools are cheap. If you watch enough of these videos it all gets explained. I happen to be shooting Carbon Express Hunter KV 250 shafts because I got an excellent deal on them. Standard arrow build with a 50gr insert and feathers gets about 17% FOC. 460grs total weight.
I'm shooting carbon, Gold Tip Traditional or Carbon Express Heritage. I prefer the weight (gpp) i get from the Carbon Express. I think some of the aluminum may weigh more per inch but I've already got my poop in one sock for this season.I
I shot xx75s for years 1916s when I was 13-16 2313 as I grew. I switched to the radio x weaves and prefer them. They will break but dont bend and can take a solid hit that will destroy aluminum. Once I was testing shooting a new bow at the shop. My shot went between the target hit the block wall bounced back 3/4 way down rand with no damage other than a flat spot on the field point.
Aluminum works great but carbon seem to hold up better.
Thanks guys! I guess I'm old school too, I love my xx75s! I thought I'd see what else is out there. I thought of going carbon and front loading a bit. I'm no closer to a decision but leaning towards the carbons.
