Most rba's will wick high VG juice quite well, it's more of getting your build and wicking correct for the rba used. I mix my juice at 70-80% VG, and all my rba's handle high VG at 20+ watts without a problem. My first rba was the Russian, a great rba and is still in my daily rotation. The flash-e-Vapor V2 is probably my favorite in my collection, I have both the Authentic flashi from Germany, and the Fasttech clone. Both produce a great flavorful vape, and vape great at standard or sub ohm builds. The one from Fasttech was only $25 and can highly recommend it. While not a exact 1:1 clone, it is well built and vapes as well as the Authentic version. Only thing I had to do is drill out the air adjust screw to 1/16", to get a better air flow. I also have the Aqua and the Taifun GS, both are great, the Aqua is a dual coil rba, and works quite well at low sub ohm builds.
For a first rba would recommend the flashi first over the Russian/kayfun, just because it is much easier to build and is a solid performer, although the Russian/kafun style rba would be a great choice too. The Aqua is a bit more advanced and wouldn't be a great choice as ones first rba, the Taifun GS is similar to the flashi but on a smaller scale.
Lots of fine rba's to choose from, find the style you like best and go with that.
Vape long and Prosper!!!
