Have you had Velvet Merkin, the barrel-aged Merlin? Outstanding. I only had a sip of it at FOBAB, but look forward to the promised wider distro this year (though I don't know if it will be bottled). I'm a huge fan of the FW anniversary beers (gotta love a beer that comes with the beer equivalent of an MSDS), Abacus/Sucaba and Parabola. Got a few of each squirreled away in the basement laundry room, er, "cellar."
I did get to try the Merkin a couple of times on draft. As you mentioned, it's outstanding. They haven't bottled it in the past but should be doing so for the first time in September. I hope "Sticky Monkey" gets bottled next.
