Wow - first off congrats to Aric on the pending new arrival! Best wishes for a happy, healthy mom and baby!
As for small cams, I followed Julie's pattern and put my aliens (black through red) away after reading some of Aric's test results. I invested in a set of mastercams covering the same size range, and so far I'm totally happy with them. I have tcu's also (I'm a bit of a gear whore, you can probably tell), and they come out if I have the need to double up in the small sizes.
I have C4s from .5 through 4 for the bigger sizes, plus a 5 tech friend that very occasionally gets used. (The .5 C4 overlaps with my biggest Mastercam, so sometimes one or the other gets left on the ground, but it seems to be a frequently used size for me, so I often carry both.) When I'm doubling up in bigger sizes (.75 through 4), I use forged friends.
