Let's see...
The alliance from Ypsi of the curling bots: 279, 66, and 322 were all awesome.
The Huskies, 65, were pretty good too... as were wildstang and team rush (111 and 27... fun to watch them play together, too- Ypsilanti and Chicago).
I'm still in awe of 190 hanging in autonomous.
Beatty could hang fairly well (Witnessed: chicago, nats)
... as could CyberBlue and 'Da Bears (chicago)


As for at the nationals:

Galileo:
I was impressed by 1305, 1359, and 868 for consistency.
I also watched 358 and 157 hang in situtations I thought they'd NEVER be able to. 852 hung very quickly a couple times.
64 was so creative.. I loved watching them move back and forth along the bar.

Archimedes:
111, 71, and I got to see 33 once, which was awesome..I never thought they'd hang that quickly.

Newton:
Very impressed by the hot bot, and there were a few more in the finals that were good too.

Didn't get a chance to watch Curie at all ...

There were way more good hanging bots this year than I thought there would be, and trust me...I'm sure I'm forgetting a lot off of this list.
