Ive found the draw to be a bit stiff at times also. Especially with a new atty, it takes me a bit longer to break in a new atty on this device than my other 510 devices. I think an adapter between the atty and switch would improve the airflow, but thats just me. Ive been looking for a 510 to 510 extension but all Ive found is that gooseneck, which looks cool but I dont know if I would spend 20 bucks on it.
EDIT: I should let it be known though, that Im only using this device at 3.7 volts these days. I tried it out at 6 and it was just too hot for me. 3.7v with a low res atty is my sweet spot. At 6v the draw on the Omega is nice and smooth, at 3.7v its a bit stiffer than my other devices. Its not bad though, and I do think with an extension piece it would be just about perfect.
