TBH, the alu freehubs will be fine, as long you use those cassette that have an alu sprocket carrier, put copper slip on the spindle and torque the cassette on (if not tighten properly, result in the sprocket moving back and forth, digging in).
I have used it on touring too, it's also fine.
I run cheap cheap 10sp cassettes. Steel against steel.
Then just put copper slip on the spindle and torqued the lockring, it'll be fine.
