I got the penelope-clone Euforia from vaporfreak and I'm pretty much sold on the GG-atty design. Followed with a term-c that vapes very nicely as well. I'll most likely end up with a genuine penelope. The NR wires take about a minute to wrap together, and I've only been doing it a couple weeks.
I haven't tried them all (spheroid, etc.) but for a pocket-friendly no-leak design the penny is solid.
