having a slightly longer distance to the herb by about 1/2 inch appears to make a subtle but important difference. The ABV is more uniform and my hits are bigger at lower temps. By the way, when the screen is seated as pictured (not my pic, BTW) inside the M2M, its in about the same position as the screen in the SSV bowl of the GG heater cover/wand. Another factor might be that when the screen is in that position, its nearest to the tightest point of the GonG connection, right where the adapter seals the heater cover. It's possible that 7th Floor figured out that this was the optimal distance between heat source and herb, since its set up that way in their GG SSV and DBV designs. If so, it would stand to reason that similar dynamics and load placement would work with the LSV.
