I have a few different stems, I don't have the exact WPA as featured on the Troy & Jerry show, but I do have one, and use it fairly often with a small shower head bubbler. It's great for ripping through a bowl in 2-5 hits without a cough (usually). Really terpy buds or back to back bowls increases coughing likelihood.

I'm considering picking up a recycled next. I hear there is better flavor and less chance of coughing.

I started my TM2 experience with the vgoodiez bundle. I have a 3D XL stem and bubbler as well. The 3D XL stem is a bit bulky for my taste, but it turns out to fix my DTV5 with silicone perfectly. I personally also enjoy the bubbler. I know some people don't like it, but that's probably because they are trying to rip it like a bong. I think it's a great halfway point between a session and a rip.

I'll add more pictures at a future date. I'm trying to trickle in more content and be the change I want to see in this community. I encourage others to share pictures of their gear.
