I haven't piped up in quite a while, though I've been stalking this thread ;-)
I got my hands on the XL and just finished writing a review. I still have to do pictures, but it won't come out until the new year (don't want it to get ignored over xmas).
Anyway, I have to say I hope they roll the improved feeding mechanism into the regular V-MOD. I tried to get the XL to leak and couldn't, I flooded my cartomizer trying
And it was an XL length carto too, that takes a lot of work to flood. I'll post the link to the review when it's cooked and ready.
