Get a Spheroid. Most 14500 mods are 16mm, not 17mm. The Penelope is 17mm and sticks out on my Temon 14500.
Spheroid is 16mm, holds 3ml, allows you to rebuild without draining juice, accepts micro-coils easily and is IMO a fantastic atomizer. I own two, and they're basically all I use. I have a Kayfun Lite that sits empty, because it's a pain to fill compared to the Spheroid and holds only about 1-1.5ml more, and I can't rebuild the K-lite without draining the juice.
I only mentioned the Penny because it was 17mm, closer to the desired 19mm that would match a VS. I have 3 Spheroids myself, and cannot recommend them enough, they are amazing.
