i tried out my bent guildhall for the first time yesterday w/ some peterson CC and noticed that it gurgled. this is the first time i've dealt w/ gurgle. i was able to take care of it w/ a pipe cleaner so it wasn't a big deal. i had some peterson CC the day before in my straight falcon w/ no issue so i don't think it's the tobacco. so, do certain pipe shapes lead to increased risk of gurgle? do pipe shapes have any other differences in smoke quality or is it mainly cosmetic? thanks!
