can carbon arrows be shot through an auminum wb rest accuratly or are you going to have arrow flight problems

Depends on the diameter of the WB opening.
Is the diameter of the WB opening much larger, barely larger, or smaller than your arrow?

Do a search for that rest on this site. I think some prefere the larger one even with carbon arrows. At least I thought I read that once. I don't read all the WB threads though since I don't use one.
