You've got a lot of tobacco in that list. Tobacco juices, no matter where they come from, no matter who makes them, and no matter what flavorings are used, absolutely MUST steep. I DIY most of my tobacco juices these days, and I will not even consider touching them until the 4-week mark. Nutty and chocolate flavors get the same treatment. I learned this lesson through trial and error over a period of months, the hard way: Lots of juice down the drain that probably would've turned out well if I'd known what the heck I was doing.
MBV is like any other vendor, they have some stuff that I really like, some stuff that I really hate, and a whole bunch of stuff that I can take or leave. I will admit that I don't care for any of their tobacco juices, although I find their RY4 interesting enough to drip on occasion. I'll also admit that they have a couple juices that are the best among all other vendors' equivalents that I've tried, and easily cheaper to boot.
So let 'em steep. You still might not like them, but at least you'll know for sure!
