Indicators: are the metal ones better?

[RadioBlue]

I'm old school and still use the 3-wheeled 3-4-3 plastic indicator. (However, I always suggest to newbies they use the 2-3-2 if they ask.) I have a dozen of them and I permanently keep at least one in each ball bag. It's come in handy, at times, if one breaks or my partner needs one. Plus, I keep several in a small pocket in my gear bag.
I, also, use it as a tool and can change it and reset it without looking. I do not buy into the line of thinking that "not using an indicator makes you a better umpire." (Sorry, Ozzy.) I agree that the possibility is there that it could potentially keep your head in the game more if you don't use one, but the more troublesome outcome is you lose the count. I'd rather have the count correct and avoid trouble than attempt to boost my ego by attempting to keep the count in my head.
