Love me Tripoli! 
It's a Turkish tobacco flavor. Don't let that scare you though. It is very smooth! They also have one of the best custards I've had called Charlie's Custard. A must try for any Custard fan! I agree with the juice consumption on some of these tanks out now. Almost have to take a second mortgage out on your home. I tend to stay above 1 ohm but have ventured a little into the subohm realm. I just like my vape that way. I also DIY. You should check into it if it's something that interests you. It's very easy to do and you can make juices for less that a tenth of the cost and just as good if not sometimes better. Do your research though. Safety and knowledge will keep you very happy when making your own juice.
I mix by weight. Less mess to clean up (virtually none) and less waste for sure not to mention its just easy for me. Some mix by syringe/ml but the waste of syringes would just kill me and acurracy seems to get off a bit when moving to bigger batches. There is also a section for recipes in the section. You might be able to find a strawberry/caramel Custard recipe that will give you a guideline. Oh...try Nicoticket's Strawnilla. It won't disappoint.
I'm not sure. Shoot them an email. I'm sure they will respond in short order.
