Distributor question

The real question is "what is the reason to run it"? Plastic dist gears do not have any problems that I am aware of. Old/ brittle gears yes, but not fresh gears. This is my way of thinking. There is very little "load" on the dist gear when using an electronic dist (even with points very little). But lets say you have a problem with the distributor (cap/rotor interference for example) cap/rotor breaks, jams the dist, and messes up the shaft or in the extreme the cam gear. With the plastic gear the only damage would be the gear itself.
I do have a couple of metal dist gears that I have had for many years, and never had a reason to use them. I think they are a "fix" looking for a problem that doesn't exist.
