To answer my own question as to "what" rather than how much:

English and Balkans and VaPers as they will age reliably - not sure what to do about any Burleys I fancy.

More recent offerings that might not get registered

So, I'm going after:
- Gaslight, Sixpence, Temple Bar, Hermit blends, Seattle Pipe Club, Frog Mortons, Wilderness,etc
- Any Esoterica that pops up (because it is hard to find and will be good to barter with other pipers when all the tobacco we like is gone from the shelves....)

I think long standing dependables will stick around, so aside from wanting to see how they age, NIghtcap, EMP, Elizabethan Mixture, Escudo etc are likely safe.... (??)
