After my shoulder surgery left me with one arm for several months, I tried using my herbie direct draw with some tubing. You would get better hits without the tubing, the vapor is too thin for tubing, and most of it condenses before it gets to you. I wouldn't recommend it, nor recommend using it in direct draw.

I see they released the multiple bag and large pump kit. I know that can't be good. The stock pump is 1cfm, and that pump is 10cfm. Has anyone tried using like a 2-3cfm pump with two bags? I know the vapor will still be thinner, but it wouldn't be as bad as sharing a bag with someone. Pumps are so cheap, I just need to order that multiple bag piece, and I'm going to try it with two bags instead of three and a slower pumps than what they offer. Has anyone tried that kit, or using a faster pump?
