You can use your MVP for the Russian, unless you plan to go below 1.3 (?) ohms with the coil. You can pick up a clone nemesis mech for like 20-30 bucks if you really wanna go sub ohm. So buying a new APV isn't going to be that much more anyways. The Russian is a tad expensive, buy you will be very satisfied with the hit, ease of adjusting air flow, and filling.
