The big question is this: do you want it to full-on sound like a vintage plexi? If so, then my recommendation would be the new Invader, with it's decisively Green-Back qualities ... my personal favorite Marshall tone is a 45 through a GB loaded big-box 4x12. Another good option would be the Retro 30, it's like a good British made Vintage 30, only oh-so-much smoother and sweeter.
Now, if you want to take it a little more in the direction of a "modern" Marshall tone ... then I'd recommend going with a British Lead.
And, of course if you want to warm it up and give it a nice solid bottom, then ... choose my beloved ET65.
