I would probably only attempt public travel (Flying) with a Dynavap vape. And I would disassemble it and put the separate parts with similar looking yet unrelated items in different spots in my baggage.
You'll find differences between the SS and Ti tips when using them with a Vapcap. However, as long as they fit, I doubt that you will experience much difference between the two when used with the Woodscents log.
Entry level means that it's convenient and easy to use. It doesn't that it's not a top-tier vape.
One of the many reasons that it's a great entry level vape IS precisely because it's a top tier vape that is simple, easy to master, and efficient.
Everyone's unique, and different vapes are better for different people depending on that they like.
I've never used a Solo2, but I have used a Mighty, and I would prefer my HydroBrick Maxx (stickybricklabs.com) over a Mighty any day of the week.
