The Goblin gives an amazing vape when you have it running steady, I second the patience thing though. Takes a bit to learn how much space you really have and how to wick it. Once you wick it correctly it's rock solid, no liquid obstructing the air path. Biggest coil I put in and currently have is a 26gauge, 8 wraps, 7/64 ID. Any bigger and it hits the chimney base.
I also agree on the Lemo for ease. I own the V2. Both of those are affordable and you're asking at the right time because these tanks can be found online for very good prices compared to release prices.
