Time for a new steering wheel, What do you recommend? Options

[airsix]

Had a lot of fun autocrossing yesterday. I did spin the car once, and that's what prompted this post. Going from lock-opposite-lock I actually spun the horn-hub off the wheel. So, it goes something like this:
1) Whoah, I'm too hot...
2) get loose
3) opposite lock
4) reverse-opposite lock
5) both feet in, spinning like a top
6) horn hub spinning in mid-air like a helicopter rotor, apexing at eye-level where it seems to hang for a moment spinning in front of my face.
7) Driver regains focus and motors out of dust/smoke cloud after throwing horn hub out of my lap.

The painted Porsche crest spinning in front of my face was quite distracting (but I was proud of myself for getting my feet in and keeping the motor running).

I've been wanting a smaller wheel for some time now. This event was just one more incentive to move on it. Any tips on what you like vs. what to stay away from? I wouldn't mind the wheel being placed and inch or two closer. I've already got a deep seat and do plan to eventually cage the car. What diameter should I shoot for? (the stock wheel is defineitely TOO BIG).
