Exactly, a good squonk atty is the key. I'm not a real fanatic on drain back since cotton will absorb the juice anyway but as long as you pay attention you'll have fresh juice all the time. It beats dripping for sure.
Speaking of dripping, I built the NoPity with a pair of SS Clapton's & it's pretty nice. I may need the cloud cap because it's just a little tight with all the holes exposed on the largest setting. I can see that I'd never take it out with me until it's bottom fed because some juice has been finding it's way out of the bottom air holes if I'm careless when I drip. For relaxing on the couch & dripping it's a dream. Also, I think any bottom air atty with this design will leak if juice gets in the air intakes so I'm not faulting the NoPity for that.
