Well while this does not exist yet it does combine some of your ideas and some of mine as well as some of what is already out there. Some of the ideas presented for this style e-cig are as follows:
1: Dual Atomizers (Note that both atomizers come together into one mouth piece.)
2: Larger Cartridges (Creating a new cartridges that bridges the two atomizers together makes for a larger cartridges for your e-juice)
3: Easily Refilled Cartridges (Note the chamber that holds the two atomizers together. This has a lid on the top which can be unscrewed to refill the cartridge quickly and easily with out creating a mess.)
4: Choice of Automatic or Manuel (one of the 3 switches under the rubber grip gives you the option to either draw automatically or press a button to receive your vapor.)
5: Atomizer Options (There are two other switches under the grip on the battery that give you several options. One of these is to use a single atomizer or dual atomizer or both. Both will be explained in example 6. If you choose single there is a switch next to that that has the option of which atomizer you want to use. In other words it gives you the option of left, right, or center which if for dual mode.)
6: Use both atomizers (while there is an option under under the drip on the battery to use both at once you might want to conserve your atomizers as well as juice and battery life. The option presented here is where one atomizer will let you vape for a set period of time and then switch to the other. This method is is by far the most effective method and the prime example of what this device is meant to do.)
7: I hope you like this I would be glad to explain things out in further detail.
