I'm going to the IR route myself, to have a more defined and tight bottom end that I'm not able to have with 11R stock cabs and EQ (I found good sounds, but with the right IR is even better).
For slightly overdriven patches I didn't find an IR that suits me well and I'm using the B30 2x12 with a very big cut over 10khz and in the 2khz range (if you want I can post the exact EQ this evening).
Given the incredible amount of IRs out there finding an Ir for every single patch is difficult: I prefer to find one or two that I like and build the patches around them, as I normally do with a real amp
