I tend to have a pretty good memory for these sorts of details, but without any actual experience of these later types, it's hard to get it all straight...

I'm interested in acquiring some of the post-2001 (round top) 9spd levers; how many flavours did these come in, and what the hell does it all mean again?

Ultrashift, Quickshift, Escape, WTF?

Ideally, I'd like them to shift the same way 1st-gen Ergos work, if that has a name... but I take it these ones won't, is that right?

What's the deal?
