Has there ever been or will there be consideration for a tube mod style product? I don't mean anything VV, but similar to something like the silver bullet. My reason for asking is that I am looking for something beefier than the X2s, and something I can personalize like with laser etching or custom vinyls which won't go to waste by throwing it away when the battery dies. I could just throw in another battery and my one-of-a-kind personalized pv would live again. Other than juice I have been dedicated to SI exclusively and would like to not shop anywhere else.
I was hoping for a 2600 mah bat. Nice and thick.
