DMM IMPs, RPs or the black diamond equivalent. Minituarised versions of regular notes are rubbish compared to micros designed from the ground up, they're weaker (important as small gear is pretty weak in general) and don't place as well.
I've got some brass ones that aren't offset and they're too tapered to fit into pretty much any placement I've ever come across. They're shit, get something offset. Dunno what brand they are, but you get the idea.
I've also got some of the much less steeply tapered tiny BD stoppers (I think) which are good.
