Sweet or Mild Specialty Peppers

Seed catalog fever has struck again. I grew over 30 varieties of peppers a few years ago and discovered some were too hot (Lemon Drop) and some had a fruity flavor I didn't enjoy (Caribbean Seasoning peppers). I like bell peppers and peppers with thick walls that can be roasted. Zolotistyi ripened yellow with a touch of fruity flavor, a wonderful pepper, but I don't think I cooked it the way it deserved. I'm still experimenting with sauces but in late summer I seem to be mostly sauteing garden peppers and making pepper and sausage sandwiches. Are you growing a special pepper for a special recipe? Do you have a recipe that just isn't the same unless you use Pepper x? I might order seeds for ten new peppers. Am I foolish or what?
