Mini Humbuckers offer you the best of both worlds; they are humbucking (i.e. no 60-cycle hum), they are capable of great chime and clarity when you play clean, and when you use a lot of drive, they sound fantiastic. They will never sound quite the same as a full-sized humbucker, but they have a fullness and grit all their own. You really have to experiment and find the ones that are best for you, but it is worth the effort.
