Actually the mini with ext. cap is about 1/4" shorter than the full size without the cap. I have large hands, I wear XL gloves, and the mini fits my hands nicely. I also like how I can throw it, and a tank, in a pocket T-shirt and don't have to worry about it falling out all the time. Also, with 6-7hrs of runtime from the 18350's, I'm good with the size.
I personally don't care for the looks of the twins, but always wanted to get the Kir Fanis 18650 ext., not sure if I will or not, but it's a nice option, I have 18650's, and it uses the standard battery cap so it's not tippy like the Provape ext. cap.
