I hear ya.
Before I started roasting my own, I thought all I liked was French Roast. Now, all I drink is roasted to city + to Full City +. If I accidently go beyond that, lets say Vienna, I dont toss it out by any means. I either used it to blend with other lighter roasts or give it to someone who I know will enjoy that darker roast.

Its amazing to see how many people get basically converted from "all I like is French" to "Wow" that lighter roast is great".

But dont be afraid to brew up those darker roasts to see which beans can handle it better than others.
Sometimes you cant get those "chocolates" to come out until you reach that Full City / Full City+ or even Light Vienna ranges.
