Lol I did similar, jumped from egos to provari mini after 2 months and very shortly after got another 2 full sizes. Such a huge difference! I've seen others move up in increments, with evic, vamo, svd, and so on. In the end many have said they wished they'd just gotten a provari first as it'd have been cheaper in the long run!
I'm into RBAs and mechanicals now but still use my provaris all the time, so it was a great investment IMHO. Still, I am tempted by the zombie edition, it's awesome. Congrats on getting it!
What kind of tank are you using btw? I really like the kanger (protank 2&3), though I did have issues with leaking from time. Nice flavor, easy to take apart and clean, and they look pretty nice too.
