Please don't take it the wrong way, but how small are your hands? Really, not flaming you, whatever works for you, do that. Just trying to help.
If you prefer a Reo/RM2 to an Ego/clearo, have you tried Reo Mini? I have a Mini 2.1 sitting on my desk, and, while my hands are only slightly smaller than average size, I can hide the entire
mod in my fist. The original Mini (the 14500 variant) was noticeably smaller than that.
If not, I could also recommend VMod 2.0, which is even smaller than that. About size of two 600 MAh Egos side by side.
