I'm enjoying my Paramours, but my Digiflavor Z1 SBS with a Siren 3 RTA is built like a tank. Great combination. It's just taller than the Paramour by about 10mm.

I have over 20 18650's, and they're perfect for all my 12 watt MTL mods.. Don't own (or want) any 20700's or 21700's. They're usually more expensive, and mods with that battery capacity are always taller.

Now, I can easily see all the DL people loving larger batteries, or duals.
