You don't like Tank 7?
Love that beer, it's everything I want in a nice saison. Curious what it was you find in Tank 7 that you don't like (but you apparently still like saisons); too funky?
It general, it's real hard to "hide" a flavor you don't like by covering it up with something else. And to me, at least, adding vanilla to a saison-based recipe... I probably would have tried dry-hopping, first.
