I've used the Nautilus and Aerotank on my 134, both work pretty well. I'll see if I can pry it out of my stepson's hands next time I get home and try it with my Subtank Mini and the 1.2 coils, see how they do.
In other news, has anyone modded a 134? I love the design, I just wish it could do a little more power. Maybe take the brains out of an iStick 30 or 50, or maybe even a Smok BT50 mod if there's enough room in there.
