If you're mixing, I'd go with a Whipped Cream flavor rather than Bav Cream - the BC tends to be pretty very vanilla, almost custard-like. WC is more like a straight cream (smells like butter in the bottle, lol). I wouldn't recommend Sweet Cream as it tastes like butter. Oh! And avoid "Caramel Candy" flavoring -- it ruined literally everything I tried it in (tasted like burnt sugar) and I PIF'd it as soon as I could!
I am speaking from experience, but my flavoring is all MBV and I know that makes a difference to some folks...
