I've played H2H for several years now, and I will typically use roto rankings.
A couple of things to consider:
1. Streaky players like Howard and Dunn can kill you in H2H.
2. Favor power guys over pure speed guys.
3. Drafting a balanced team is extremely important in H2H (it is in roto as well, but being balanced in H2H will keep you competitive every week).
