The tugboat, slammed cap, and v1 mod finally arrived this past Monday. USPS literally never updated. :/
Anyhow, I've used both the stock cap and slammed cap quite a bit the last few days. I'd say, the vape is VERY similar to the derringer with the slammed cap but having a little deeper
juice well helps in avoiding over dripping. That being said, I've found that I prefer the stock cap. The slight resistance in the draw does make this atty shine flavor wise and when adjusting the airflow on the derringer to match with the same build, the derringer tends to get way too hot. I seem to get a comparable vape vapor density wise on a 6 wrap 24 gauge build in the tugboat as a 5 wrap 22 gauge build in the derringer (wide open to avoid the hot atty) making the ramp up time slightly, yet noticibly quicker. The build quality on the derringer is quite good but I think the build quality of the tugboat is just a hair better. The way the barrel sort of "snaps" onto the deck everytime is strangely satisfying.
Overall, I give the tugboat v2 two thumbs up and it has bumped my derringer into the number 2 spot in my favorite atty rotation.
