Great to hear the Masterworks program will be be around for a while yet.
My own picks:

No 96: THE MIGHTY THOR Vol.7
No 97: THE HUMAN TORCH Vol.2 (Silver Age)---I'd prefer to read Silver Age Subby Vol.3 but the completist in me would push for this instead.
No 98: WARLOCK Vol.2---to complete it and also because I've heard it's really good.
No 99: NICK FURY, AGENT OF SHIELD Vol.2.
No 100: THE AMAZING SPIDER-MAN Vol.10---since it was the first masterwork, it would be fitting to be the last. A good excuse for a really big volume to complete the story arc through Issue 100.

Of course this would leave out Golden Age Cap Vol.2. And Kirby's Thor wouldn't be finished.image
Just as well the Masterworks are gonna keep on coming!!image
