In reply to apd: Get some HB (dmm) brass offsets, they're probably the best all-round micros you'll find. Getting 1-6 would be a good range, from very small up to about rock 1/2 size.
RPs or the Metolius micros are options for a more 'normal' shape micro, but I find the HB brassies are almost always my go-to wire of choice.
