Update: did some quick and dirty taste tests... (in order, best to worst)
1. peanut butter banana (actually very good!)
2. lemon (with a bit of vanilla custard) best of the fruits
3. berry mix (works very well)
4. mango peach (seemed like it was fighting with the mint)
5. vanilla butter nut (needed something... kinda boring)
Partial cred it to Atty Pops for suggesting peanut butter
Going to try a few more tomorrow: RY4, vanilla custard and green apple (candy) Can't stand green apple myself (prefer apple pie) but who knows... didn't think peanut better banana would be so good
Side note: also tested my french toast and apple pie with FA cinnamon ceylon... worked great! Very subtle.
