I was screwing around with the transfer wand last night and had a couple of thoughts.
1: the screen inside the actual heater cover should be a finer mesh. The almost-MFLB grind I use allows a portion to get sucked through, leading to waste and a nasty aroma of burnt material.
2: the LSV transfer wand should have its screen placed lower within the male GonG joint. This way there is less area for the herbal material to "fly around", so that it's sandwiched with less area, allowing more consistent results. An Arizer Extreme Q elbow bowl works really great for this task!
While the WPA definitely dominates my LSV usage, the transfer has its place in the world! Also might as well mention that I have only the shorty transfer, and have literally zero wish that it were any longer - it works just fine.
