What's the largest bowl size that you've found in a USA made cob? Also, what kind of smoking experiences have you had issues with larger bowls vs. smaller? I ask only because the 4 that I've had for a while are MM that have small to medium sized bowls. I bought a Dane Egg straight stemmed a week and a half ago and it's bowl is fairly large. I've been disappointed with the way it smokes, seems to run hot, doesn't transfer that sweetness I get from my other cobs and it's getting so that I'm just giving it a pass when I'm reaching for a cob. I use these as knock around pipes when I'm working or messing around in the yard or out in the field with my dogs. The only characteristic with this egg that's different from my others is that the bowl has that MM blackish stain on it. Could that be a factor?
