So I've had multiple vapes in my possession for quite some time but I've always used just one of them per session............until just recently. My current rotation is as follows: Fire up LSV and use for my first two hits. Let it cool off and put it away. Use my MFLB for maintence hits as needed. Why do I do this? Because I LOVE the taste, quality and quantity coming out of the LSV for the beginning of a session. But for followup hits when stoner laziness sets in, for me, there's nothing as convenient as hitting a pre-loaded MFLB. Not only that, but I've found that the high from both of these vapes are so different from one another using the same bud, that using them both in one session has the same affect as vaping a salad of different strains, which for me, has always provided a more powerful affect than vaping a single strain alone.
