My purchase (based on google and youtube but not based on this thread since, sadly, I did not find it til today):
[15mL bottles with a variety of PG/VG ratios though I did buy some basic unflavored VG so he can tweak it however he wants, all with either four or five shots. I know most people start with reg flavor and then work up, but I think with his tastebuds he needs to start high and come down-- once again, the VG should help him if he needs it since he's okay with higher VG though as far as I can tell he hasn't had any sensitivity to PG]
1. 555
2. Thug juice
3. Butter Pecan
4. Cotton Candy
5. Hawk Sauce
6. White Out
My advice is to not even GIVE him the 555 for at least 2 weeks after it arrives. I find a lot of people get excited, try stuff as soon as it comes in, and judge the juice by the first taste. Tobacco flavors need AT LEAST 2 weeks to blend properly. MBV recommends steeping up to 30 days for their tobacco flavors.
I also found that - for me - extra flavor shots take longer to reach it's peak / final flavor. I loved both Butterscotch +2 and Amaretto +2 within the first couple of days - but by the end of week two, they'd matured so much that the flavors were FAR too strong for my taste. So if he tries them and isn't wowed by the potency of the flavor, know that they're likely to get stronger with time.
