Don't forget to check your state's tire coverage laws. For instance, here in the Commonwealth (blech! LOL) I can't have more than 4 inches of tire tread sticking out past the front outer edge of my fender flare. Some companies sell narrow fenders that I can't pass inspection with.
That being said, I really like narrow flares. They make the tires look bigger, throw tons of mud, and generally make the heep look like a buggy. (I also don't mind a dirty jeep) On the downside, you gotta draw yourself in if you don't have doors and go through the goopy stuff!
Also, consider what you want out of your flare. If you go plastic and smack into a tree, they won't transfer impact into your sheet metal. They will likely pop off. Maybe they will crack, maybe they won't. If you go steel, they are less likely to take damage, but they may possibly transfer those hard knocks right into your tub. Aluminum costs more and will do the same thing as steel (but are much lighter, if that matters to you).
I like Ace Engineering and Fab. They are high clearance, steel, and about half the price of many competitors. You gotta get creative about reattaching your fender liners though if you want to keep them. The only reason I went with steel is because I couldnt stand to pay that much money for plastic bushcrackers. I really like Smitty's extreme set, but they are REALLY narrow (I think too much for me), surprisingly heavy, and completely replace the fenders.
YOU CAN'T HANDLE THE TRUTH!
