Small cabinets, and what to do. Advice please

[jmsjabb]

I have a session 12" guitar cab with a 12" Eminence neo driver fitted. ( 18.5" x 18.5" x 13", full width front port. ) It does the job, but i'm not too sure it is the best compromise. With nothing else to compare it to, I thought I would ask.
As I see it, I could get a 2x12 or 2x10 cab, something like an ABM. Refit the guitar 12" into the session and sell that on, and sell the neo.
I could get and old or empty 2x12", buy another neo and do it that way. ( This would give me 4ohms in one cab, which wouldn't be a problem at the moment )
I will be using a Little Mark 250 with it. I don't want real punch lows, more a good alround slightly clean sound. I will be using a 4 string.
Over to the knowledge please.
