You can really change the character and feel of a cab via the SIC.
I've currently settled on the 4x12 Rumble EV12L Dynacab, using a single ribbon mic and with the SIC #66 4x12 Brit TV for all presets, amps and tones (clean, bluesy, rock, high-ish gain, etc.).
I've found that cab is suited for all types of tones/amps, and with the ribbon in the right spot it gets a full bodied fundamental-rich tone with a forward mid that I like.
The SIC works for my various amps/tones (Deluxe Vibe Verb, AC-15, Dizzy Blue channels) to kind of balance them all out.
It works particularly well for tubby amps when the SIC curve has big, broad peaks from ~65Hz -> ~100Hz, and has nice crunchy mids and an inoffensive high end.
