For concentrates I really like the Linx Hypnos. Not huge clouds, but great flavor. It is very small, but I think you should get a full day out of the battery even using it throughout the day. The atomizer is a little fragile, but I don't get any bad flavors until I'm trying to empty it before cleaning. At some point the flavor dies out some, but I've found I still get effects for a while after the flavor has gone. It's also pretty cheap.
Yeah I’m pretty stoked to try them out! I used to like the porous SiC on the old W9 atomizers, so with clean rosin or liquid live I’m thinking they might be nice. I have the hardware in hand already I just need some material to prepare and load.
