the tugboat does pretty good on flavor, doesn't have a lot of airflow, but quite large juice well. It's a3 post deck, but I'm currently vaping on a $5 tugboat clone from fast tech with a single coil, and I like it. I can get a good cloud out of it, but it gets pretty gnarly with much more than 20 watts, you gotta really sick to keep it cool
and it is quite roomy to build on, with no leakage unless I over fill and set it sideways
