I also came back to pipes after McClelland shut and never knew about them before. I don't feel a lick of regret let alone depression about it though. I 'missed out' Cope's various glories, too, but no depression. The world is what it is and I'm in it where I am.
I'm happy for those that did experience it, and am delighted that such things have existed!
What I am a bit frustrated about is what I have tried and liked, like Dunhill's
The Aperitif, and
Three Year Matured Virginia, have been discontinued (for no good reason at all?). Clones are just not the same. Oh well. Out of my control (and personally not going to pursue them like
@condorlover1 did with War Horse Bar). C'est la vie.
Yet there are still so many great tobacco blends out there, some old, many new, that there is no point, to me, in longing for the bygones I never even met. I'm still (and probably always will be) discovering what IS available, and even creating personal 'great for me' mixes like
Bayou Veermaster and
English Mocha (likely to be superseded by
Blackadder)!
p.s. also, I'm a mustard guy and ketchup has never done much for me, so there's that.
YMMV
