First of all, I dont think very many, if any at all, of the members on this site use closed systems like the Vuse, so it's not likely that you will find someone who can directly answer your questions. It seems to me that you have found something that works for you, so I'm wondering what it is that you're searching for. There are pod systems that can be filled with any flavor of juice you want, but there are some many systems and so many brands of juice, but trying to match your current setup is going to be difficult. There will be tradeoffs. For example, I use the Vaporesso Lux, which is similar to your Vuse, but at the same time, it's a lot different. It has a much bigger battery, thus more power and/or more vape time, but the tradeoff is that it is too heavy to just hold in your mouth. It can be filled from any bottle of juice, any flavor, any formulation, any strength. I DIY my own juice. To help you, we need to know exactly what it is that you want and what it is that you dont like from your Vuse. Keep in mind that there will probably be some trade offs, ie more power but bigger size/weight. The trouble with closed systems is that you can't change the device independently from the juice. I'd recommend to first find what kind of device you want and purchase that, then see about trying to match the flavor. It is highly unlikely though that you will find an exact match. Again, what are you willing to give up to get what you want.
