I'm going to cheat…I want 2 things.
First, I want a DNA-20D in a tube mod that's about the size/form-factor of a Silver Bullet with 2 extra buttons above the fire button to adjust wattage and 5-click on/off. I'd probably put Vivi Novas with SS Mesh wicks & Kanthal wire on it. It'd be nice if it could take an 18650, but that might make the mod too long, so I'd be happy with 18490s. Realistically, a Kick 2.0 that went to ~15W and a Silver Bullet would be good enough, though.
Second, I want a small collection of 14500 batteries with set output wattages ranging from 9 to 14W that I could put in a BB with an atty for dripping.
Actually, 3 15W kicks that are reliable shoved into a Silver Bullet, a Legacy, and an Empire would probably have me wanting for basically nothing but juice, mesh, and wire.
