HSM Decorations

[CraigD]

Do those of you who wear HSMs decorate them in any way? By that, I mean do you do anything like this: http://www.pbase.com/johnny21/image/82039524 or http://www.pbase.com/johnny21/image/82039509 ?

Other than local association guidelines, is there a protocol for how much/little decoration is acceptable? Just because you can, doesn't mean you should, right?

Would participating in international competitions influence your opinion of how much/little or what type of decoration is acceptable on an HSM?

I haven't ever used one and have only seen one in use a couple of times, but found the one referenced above to be a bit over the top. Have you guys seen umpires' HSMs decorated similarly?
