Is that the micro sip method that you're talking about that will cause it to combust? I don't want that. It makes the LB taste awful.
Any method will result in combustion if you inhale too slowly. The MF batteries heat up faster so you will have to inhale a little faster but only a little. Yes, you won't need to wait quite as long for vapour to start. We're talking maybe a second or so though, since with the stock batteries you only need to wait 3-4 seconds.
