I have been mixing some of my own flavors and found butyl butyro lactate to be very versatile in making flavors
10% -10% solution of butyl butyro lactate in PG
3% -Loranns Stawberry -more candy/tart than other strawberries which goes well in this recipe
>1%- TPA maraschino cherry - 2 drops per 10ml
1%- TPA Sweet Cream
3%- sweetener - ethyl maltol is a little better than the sucralose sweetener IMO
so that is ~17% flavoring in your nic base. I have only tried this at 50/50. I would suspect the flavor might need to be decreased with more PG
Be VERY careful with the amount of cherry that you put in. Just a couple drops too many makes it cherry cheesecake which is still nice but not what i was looking for. other than that some liberties can be made to the percentages. The more butyl butyro lactate, the more "creamy" it tastes.
This is also very good mentholated.
