I have not tried wraps yet but I do plan on getting a carbon fiber J-Wrap for my Provari at some point.
As for juices, try Indigo, The Vapor Chef, Heather's Heavenly Vapes and Pink Spot for starters along with the other recomendations that you've been getting. This is if you want to order online; I've had fast shipping from all of these places.
Otherwise, find a local B&M and speek with the employees and customres about which juices would suite your tastes.
