Hey LGiv (or should I say HOWDY, since I'm a neighbor in the DFW area). I would assume that you're heading to Denton to visit Vaporescense, or are you heading up to Richardson? I have visited the Denton store, and the manager Greg was EXTREMELY helpful. We sat, and he listened to my needs and wants in a PV, versus picking a PV that he had in excess inventory. While I did pay about double for my eGo-T than what you can find online through the ECF vendors, the customer service made up for the price. And quitting analogs is priceless, in my book, regardless of the initial cost. If it works - WINNER!
Take all of these questions to Vaporescense, as they have plenty of sample cartos that you can try. If your cartos or accessories are too harsh, they can fit you into a system that works best for you. I know there's a lot of trial-and-error in finding that right fit. Sometimes, having a brick-and-mortar working with you can make all the difference.
They've got over 100 flavors of juice, too. However, they generally sell the 30ml bottles, so you've REALLY got to like it to go with a big bottle. I've got a few of his flavors, but am sampling the crud out of the vendors here. Good luck on your journey!!!
