Basically, when you wick the Erl, you leave it nice and chunky at the shoulders, then trim it down to a wisp going down the juice channels. As long as you keep that in mind, you should have no problem at all, especially with your experience with other decks.
The airflow may be a little bit tight for some people. It has a delrin nut on the bottom that you unscrew to open up the airflow. But you can completely remove it, which a lot of people do. For me, it works just fine about halfway open, but I'm an MTL vapor so YMMV.
You should give it a try. I see really cheap Erl clones all over the place. I got my first two from Angel Cigs on clearance for $5 apiece. If you love really good flavor, the Erl will give it to you.
