Flavor types that are less prone to killing coils?

[Fattlestar]

I love coffee flavors and rich flavors, but they are killing my BVC's at an accelerated rate for sure. I'm looking for flavor profiles that I can try that won't eat up coils quite as fast.

So far I know these don't gunk coils as quickly:

Menthol
Unflavored

Are there any other flavor types that generally speaking may last longer?
