I try to make sure my pitching staff is stable in H2H. But I don't rely on them to be overpowering. What I mean is that I've been successful playing SP such as Loaiza or Greinke in H2H simply because they've been giving me very solid outings. Trying to win the "Wins" category in Pitching in H2H seems to be a crapshoot half the time anyway, so I just try to make sure I have solid starters who I am confident playing against almost anyone.
I rely less on RP in H2H since SVs are sometimes a crapshoot as well. Plus, you can usually pick up mid-tier relievers and get decent performances out of them (having players like Hermanson or Turnbow vs. higher drafted players like Rivera and Nathan won't hurt you by any means in H2H).
Offensively, I look for balance, but only count on one player for steals. This year, that player for me has been Jose Reyes (not terribly successful yet, but it's getting there).
I prefer more balanced players such as Abreu, Beltran, Berkman, Damon, etc.) assuming the standard categories on offense.
