KBV's Byronic series is really good, but with the way he processes his blends I don't know that they'll age dramatically.
WCC is a great rec, I'm a big fan of their vapers and have a good amount of Old Dominion stocked up. Definitely improves with some age. Rouxgaroux, Simply Red, Simply Orange are all great with a couple of years on them. I'd even mix and press them but could be 5+ years before you get serious rewards for the effort.
PS bulk is good too: Luxury Birdseye Flake, Luxury Twist Flake, Luxury Navy Flake - all top tier ager. Twist in particular is a little strong for me on the nic side, I have some from 2013/2015 that's just rounding into perfection.
That should be enough recs to help you delete a paycheck or two
