So I've smoked several times from my medium phunnel and I just can't get a "perfect" smoke out of it. I've used the mod a few times but heat management becomes an issue for some reason, and the smoke quickly goes harsh. I got the biggest clouds out of it when I didn't use a Scalli mod, but the pull was stupid hard, even after using the binder clips mod. Then, when I raised the clips ever so slightly to increase airflow, all I got was nasty unflavored smoke because the tobacco wasn't cooking. What am I doing wrong?
