Also tried TuchMi, it was pretty good.
Currently using the diet ICS build from 08/04 with the latest BLUE theme installed (found in the diet ICS thread from peterguru) and it looks and works great. Running ktoonz latest kernel (which allows underclocking to 192MHz and has more steps than faux123's v009) and smokin's CPU Editor with Battery Saver. Great battery life, great performance, awesome blue "diet" theme. Probably my favorite so far.
To be honest though the thing that made me switch and flash diet ICS over TuchMi 5.0 was the inclusion of Google Wallet (although now my phone thinks its a Galaxy Nexus
) -- still haven't been able to test it out in the wild though...
