Marshall 2x12AR

I'm looking to replace the seventy80's in my 2x12AR vertical slant cab.
This is the cheapest cab Marshall makes and is quite smaller than other vertical 2x12's.
The amp is a 30 watt hotrodded Marshall type with dual EL34's.
I would like the cab to handle 100 watt amps.
I do gig with this cab alot, so the majority of playing time is at full band volumes.
The other guitar player uses a Mark V with a Mesa vertical 2x12.
I play mostly classic/hard rock.
The guitars are usually LP Junior and Special, both with P90's, so I have lots of mids already.
Occasionally a Strat and a Tele will make an apperance.
The amp has treble, mids and bass controls as well as presence and resonance.
I'm looking for suggestions that lean toward classic 70's with clarity and fullness.
My benchmark tone is ZZtop's Brownsugar.
So many options!
Thanks in advance
