currently no just our XL cartos.. dual
coils needs higher voltages to fire properly....
How about something like the bottom coil echomizers? I'm finding I prefer single coils to dual coils anyways, but having a 3ml lr carto for the x2s would be awesome. To be fair I haven't tried the things yet, they are in the mail as we speak, but they do seem pretty awesome.
I do like big cartos quite a lot, and when I tried my EMDCC on a 510 Ego I had I did like it, but would definitely prefer something like that form factor in a single coil, and of course having it work on my x2.
I'm sure you guys will come up with something.
