I bought it the istick 30w, thank you, everyone!!!
Lezlee, I appreciate you telling me I could go up to 30w, I didn't know that.
I'll be stalking the mailman next week.

You're welcome. That spring loaded 510 is worth it. The 510's on the 20w have been the biggest problem area on those devices. I use an AFC to protect mine.
The 30w is rated down to .4 ohms and your Geni Mega should fit fine at 22mm.
