I've looked hard at getting the round Robust... often... but the fact that it's only VV keeps me from getting it and just wait for someone to make a VW in this size.
For that size, I do have an original E-Power 14650 that is unregulated and I updated it's switch to one that has an eGo threading on it. That gives me a 5-7w vape on a 2.5 ohm head as long as I don't let the battery drop below 3.6v. For my VW... I now only have a Vamo since a friend talked me out of the v1 Zmax I got through the Alpha program.
