I second what RG said about RP 'nests' -- when it comes to micros, more is better.

Also, when I bought my set I picked up a screamer to go with them. People will debate me on this point, but when I clip micros or pins its usually with a screamer.

What harm could a screamer do?

my buddy unzipped several strands of a Screamer on the super-manky, upward-driven pin at the crux of On Any Monday. It was an onsight attempt, so you can bet he was glad to have it!

Micro nuts are fine, but you can never have enough green aliens!

As for brands, I've got the BD Micros, and I like them. But take this with a grain of salt, as I use them more on NH granite than I do on the Gunks.

Actually, my opinion is probably pretty worthless, since in addition to using them for NH granite more often than Gunks conglomerate, I also:
- Am only just breaking into Gunks 9s and 10s myself, and
- Only get to the Gunks maybe a half a dozen times a season.

So there's my $0.0002. Take it (or leave it) with a few grains of salt.

HB offsets. They rule at the Gunks.

#5 is my personal wubbie. I have placed it so many times where other gear wouldn't go, I've lost track.
There are pitches where I've placed both #5's, and several of the other sizes too.
( I have doubles from 3-6, but this is admittedly overkill)
The #5 is to offsets, what the green is to Aliens.

Sizes #3-#6 are the 'real' gear, they are very strong and can hold a decent fall.

The smaller ones are good for oppositional pieces, or as headpieces maybe. (or for aid, if yer into that sorta thing)

You'd be surprised how often you can find a home for one on an 8 or 7 too; but for 9's and easier 10's (which is exactly where I'm at, or was at when I left off last yr) they are damn near indispensable IMHO.

Pick up #6, 5, 4, and 3 and a biner to rack 'em. You'll be glad ya did.

And don't bother with another green Alien, get a green/ yellow offset instead.
mmmmMMMMmmmmmm Alien offsets, mmmMMMMmmmmm

PS - edited to add: 2nd or 3rd of 4th the idea that a screamer ain't a bad idea either.... 'specialy on the smaller guys.

if you travel you'll really like the micronuts as well. many 9s and 10s in places like little cottonwood or eldorado canyon pretty much require them.
