Im happy to report I have been extensively testing my Evo unit and have found my preferred setting. 2-3 o'clock seems best at 1/4 ELB size. I get 2 solid hits per ELB. Vapor is still available on 3rd hit, but GREATLY diminishes. I have tested with both HydraBomb and Honeycomb. Honeycomb allows for a much larger hit and will "vape" my material more evenly. The HydraBomb provides decent diffusion (nothing compared to the Honeycomb) and is a MUCH easier pull than the Honeycomb. I can fill the HT with a milky cloud 2x as fast when i use the HydraBomb vs the Honeycomb.
Also, I am building out a stealth smoker closet and would like to know what features you guys would have in your own secret smoking room. Room is 66"x30"x96". So far I have planned a workbench table top that opens on a piano hinge to secretly hide my glass pieces inside, a flush "garbage" chute in the tabletop to sweep un wanted material away (dumps into a collector below for recycling, like a chef on tv), set in silicone mat for wax/shatter work, magnet board for metal dab tools, various mounted bins for extra ELBs, silicone containers, etc..., custom board/mount for HTs and EVO accessories, charcoal filter for extra vapor filtration, (wife is not a huge fan)and thinking of adding some sort of funnel system for east loading the ELBs. Maybe use a flask funnel attached to the top of a small jar? Just my super high $0.02... haha. Peace homies.
