I think twists with a good delivery device are hard to beat I.E. Protank, EVOD, T3, etc. I don't think upgrading to a Provari will be as dramatic an upgrade like going from cigalikes to a twist is. In order to upgrade from twists it's going to take $$$ and time. If youre already happy with your set up then why not spend some money on different juices instead? Try a bunch, see what you like and then if you find yourself wanting more, upgrade. I know a lot of these threads leave the impression that to truly enjoy vaping, you need to drop a boatload of money on gear, but thats just not the case. Plenty of folks on here have been happily vaping away on Ego batts for years. I own a Provari with a Kayfun, expensive? Yes, but it gives me the quality vape I need while being reliable and very hassle free. Something that I didn't get from other devices. My situation is probably unique, I am in the Army, I needed a rugged device that would survive in the harsh environments that I frequently find myself, spinners and protanks were dieing by the score, but it was mostly due to my clumsiness and the 120 degree temps. Even with a high end set up at home or out and about I will still vape a twist and will always recommend them to folks just starting out or without the need for something higher end. You have just beat the Cig monster, sit back and enjoy your freedom.
and DRINK WATER!
