As a pretty committed contact printer, I can tell you that OF COURSE you can use trad papers for contacting. And they look great. Azo is neutral at best and a little blue or green if not toned or developed exactly right, so contacting on a warmer paper can make more sense especially when photographing people.

One thing I have come to notice through experience is that graded papers seem much sharper than VC papers. Visibly sharper. You might try Oriental and Ilford's Ilfobrom, both of which I have had very good luck with.

An 8x10 contact on a graded paper (especially Azo) is undeniably a contact. An 8x10 contact on a VC paper is very sharp and glowy, but to my eye is indistinguishable from a 4x5 enlarged to 8x10.
