Once you've tried the Tatuaje PCR, there's really no other tiny NC that stands up to it, IMHO.
I've been known to indulge in a cheap full-size and just toss when done.
On the CC side, the options are endless:
-H Upmann Half Corona
-RASCC
-Party Short
-SCdlH El Principe
-Bolivar CJ
-Monte 5
Those are my choices for lunchbreak cigars. They're all larger around than the 32rg, but personally I find that too small for me anyway.
Another option if you really want something small is to get a paper roller and smoke some pipe tobacco. I do that from time to time and find it quite pleasant.
