What we have here is the package standard whip add on to the tubo Evic attached quite snugly to my (new) blue TI hopper. I'm sure I'm not the first person to stumble upon a hack along these lines, but I find it to solve two problems:
1.) As with all hoppers, my mouthpiece gets too hot to pull on after two hits. While I don't make a habit of overwhelming the heater, this does negate heat on the lips entirely.
2.) My new hopper has a difficult time extracting dark ABV on 5 and is likely underpowered. I have found that reducing draw speed beyond what is comfortable native is a solution, which can be done with the whip attachment and a normal draw. I can get MUCH better hits this way than both natively and with my 10" bong with PFE; airflow isn't even the least bit restricted.
Research will continue because science.
