WPA is quite wide open. To a surprising extent after using the stem.
For me, Thermocore is where it is at for oven. And likely most responsive to an IH.
Tornado is Vestratto's take on the Sublimator design (a.k.a. their equivalent to the Electropath). Forge, Wagon Wheel and Cascade are all IH related. Cascade is an option for the Forge IH's settings, wagon wheel helps consistently position vape in Forge for more reliably consistent...
Stock stem is lovely. I do like the XL mouthpiece if you can swing it. Unlike the Tempest or my Dynavaps, I've never been inclined to upgrade the Anvil stem. The Anvil tubes also work very nicely for back to back hits with their magnets. And Sneaky Pete sells a magnet ring that also works well.
That is basically the glass for the Stache RIO, an incredible all-in-one butane dab rig (RIO= Rig In One). Glass can be brought separately, but the RIO itself is well worth the asking price if you dab at all.

Great question. I actually meant to add that to my original post. Someone a while back recommended the Studenglass whip. One end has a nice friction fit in the 18mm female joint for a mouthpiece on the Goo Roo HDR.
That one from Vgoodiez is solid too, especially if you want a smaller diameter...
