[NM FP Ump]

Oh my, I am having flash backs to high school softball meetings, where one umpire asks for a little help on a situation and, ten minutes later, we are talking about anything but the answer.

I have an aluminum one I was give 10 years ago that I pull out once in a while, 3 wheel. But I use my plastic 4 wheel so much it's hard to use the 3 wheel without messing up. If my opinion counts, aluminum would be my choice.
