I love the 510 mega atty/mega cart combination. I like the fact that I can still use the eGo cone with them, they stick far enough above the cone to make re-filling easy, and they hold enough juice to keep me happily vaping for quite awhile with no re-filling.
I have several PVs going at one time so it gives the juice time to wick down to atty. I use Fluval for the filler. Here's how I use the Fluval:
