I got the mini because I liked the teardrop pattern better than the lines on the v2. For me, battery life isn't a big deal. It takes me 1.5-2 days to drain an 18350, and 2 days for the 18490. I like the look and size of the mini with the standard cap on it. The size is perfect with the extended cap, but doesn't look as good IMO. I will get a v2 eventually, but not because I need the bigger battery capability, because I want to have both!
