Holy Grail? I would say Escudo fits the bill - though, like Bullseye Flake, it's a coin/medallion rather than a true flake. I have yet to find a VaPer that can compete with Escudo.
As for VaPer flakes, it's tough to beat Stokkebye's Luxury Navy Flake. This blend is great fresh, and improves dramatically with a little age. If I had to choose only one, it would probably be this one. I could smoke it every day and miss nothing else.
Another VaPer flake I love is Marlin Flake. Very different than Escudo in that it's the plummy rather than spicy side of Perique. It also contains some Cavendish, which may not meet your definition of a true VaPer flake. But delicious nonetheless.
While a broken flake rather than a true flake, you'll find GL Pease's Fillmore an outstanding, stout blend. Another broken flake you may enjoy if you really like Perique is McClelland's Beacon Extra. It's a blast...
(Oh, and to answer your last question, I lightly rub out my flakes. So kind of a hybrid of rubbing out and fold-n-stuff.)
