I've looked and looked and haven't been able to find stainless steel smoktech in 3.0. I just don't like the boge. I've really liked using the smoktech 1.7 on the LT. I know they say it's not recommended to use LR stuff on the LT but I can use it up to 4.2v without going over the 2.5amp cutoff. 4.2 is as high as I want to go anyway so I'm happy with that.
Tank cartos are going to flood at some point. I've used this same one for 2 weeks now with no problem and all of a sudden it's wanting to get gurgley. It doesn't actually dump it's juice but it's enough to spit juice back at me and drip down the side of the LT. I did spot a small air bubble coming up from the bottom grommet (I use the chibi type tanks) so I figure I have a tiny air leak. Every once in a while when it starts to gurgle I stick a needle in a suck some air out and it's fine for a while. I guess I need to take the tank apart, rinse it and dry it and reassemble it. Or maybe replace the grommet (bought replacements on amazon)
something I've found to be helpful is to put the tank in a small plastic med cup until I'm sure the air pressure is balanced and it's not going to dump it's juice. That way I'm not losing any juice. I rarely have flooding issues but it does happen from time to time.
