I remember mostly because, when I was searching for new BKPs for my LP Std, I archived a bunch of notes culled from forum posts. :) The Emeralds were certainly among the pups I was considering: the stats seemed good, and your description sounded good, though it was tough to find clips -- and eventually Tim recommended me the Crawlers, so I got those. (And they've worked out very well! :))
Still, the Emerald has always seemed to me like a sorely underrepresented pup! Maybe the long-awaited site update, with more detailed info and more clips (didn't we hear new clips were recorded, like, a year or so ago?) will give the Emerald a bit of a boost.
