Brett Tomko has been night and day at home versus away. He's an extreme fly ball pitcher and pitching in LA helps him a ton - I'd stay away from anything other than a similar park (like @Fla for example).

This year he has an OPS of only .576 vs LHP but .852 vs RHP.
If you're not in a shallow all-star league, playing the best matchups with your lower ranked players can give you an edge. Its difficult when you bench Giles vs a LHP and he goes 3-5 with an HR, but you just have to ride that out.
It's a lot more work to check out the best matchups every day instead of just playing studs, but we can't all have studs at every slot.
