I have some that draw great with the drinkless and ones that don't. If it's not a specimen, I'd chop it if the airway is tight Just make sure to leave the threadsJust finishing the CH in the Kaywoodie. Smoking okay but have to watch my cadence as it has a tendency to get hot if puffed too quick. Not sure hiw I feel about the "drinkless " filter. You Kaywoodie owners, what do you think about removing it?? Thanks for any advice.
