^^^^ What Bebop and Compenstine said. The very first thing in your shopping cart, however, should be a dedicated ohm meter. Safety always comes first.

The short answer is since you have no experience rebuilding coils, taking on the dual coil pro tank 3 will be a challenge. You could rebuid them as single coils but don't xpect the same performance. I personally would not choose silica wicking material. Most people generally agree cotton tastes better and gives better performance. You would still need a coil winding tool regardless of wick material. If I were you, I would do a youtube search on rebuilding kanger pro tank coils so you can get an idea of what you are getting in to. You may find a specific video on the pro tank 3. Start there Notice his description is a 9 wrap 28ga coil on a 1.5mm rod. He's doing single coils

Having had my hands on a cuboid for all of today now, it's much smaller, as powerful, same options (plus a couple if you like the smart setup) and functions well. I can't really judge battery life quite yet, as I just put a fully charged set in, so we'll see how that goes. Right now the fuchai and snow wolf are parked cause the cuboid is the new toy so I hope to have a better grasp on how well it does with batteries.
