FWIW, I just got my K100 yesterday and I've got an 18350 Efest in it. I've used a standard carto with the drip shield (I love that look and am planning on getting a HH357 atomizer later this month) and a cheapo Squid knockoff from fasttech. The spring is plenty stiff so far. But again, it's brand new.
I'm diggin it a LOT. I re-coiled the wick that came in the Squid. It was a 2.-something and now it's a 1.8. Working great, especially once I remembered to seat the air hole in front of the coil. Derp. Go me.
