I shoot XX75 camo hunter aluminums in both my bows...
2018's from the 48#@31 longbow, about 32" long with 125 grain screw-in Simmons or Steel Force heads.
2419's from the 68#@31 recurve, about 32" long with 175 grains worth of adapters and Zwickeys on the business end.
I shoot the same shafts year after year. While I've got about a 5 dozen supply of each shaft, I rarely ruin (or lose) arrows. I've got some aluminum arrows that I've been shooting regularly for 4-5 years, and they are really holding up well for me.
