Gallardo vs. BigUnit: one or both?

[Chicago RedSox]

I have Gallardo and R.Johnson going against each other tomorrow. I'm thinking of starting them both, but wanted to know what others were doing.
Gallardo to me is a must start. The Big Unit has had a great spring, but Milwaukee's offense looked lively today. Pitchers duel?

I'm happy to return the favor if you leave a link.

Same here. Im pretty sure that Im rolling with Gallardo in my Roto, and bench the Unit in my H2H, but thats mainly because Kuroda, Beckett, J Johnson and Bedard already givin me the edge, so risking 3 IP, 7 runs out of Unit is not worth it.
But I might be wrong as usual and Randy puts up zeros w plenty Ks.

Per Yahoo: His(RJ's) opponent is the Brewers, a team he has beaten 18 times -- tied with the Rockies for most wins for Johnson against an opponent.

This gives me a bit more incentive to start him....
