I started checking out the Venvii Baby Ness, it's a single batt mod based off their dual battery Loch Ness. I really like the look and ergonomics of the Baby Ness. It's compatible with 21700/20700/18650 batteries which is always a plus and t has all the TC modes, TCR, TFR, Boost, Smooth and Custom curve settings. I don't know who makes their chip, think it was their own design, but remember the original Loch Ness had pretty good reviews. It's a nice looking mod, think it's still pre-order but went to Venvii's site and they stated they've started shipping them out.
