Dynamic Prop Balancing?

[Paul Sharp]

Wondering what opinions there are here for dynamic prop balancing? I just had to replace my front back plate for the prop spinner. Noticed some others with spinners, etc. being replaced lately. Is this just coincidence, are there a lot more that just don't make it to the message board, or ?

How many out there do dynamic prop balances? I don't think I've ever had it done and somewhat nebulous about whether or not I should.
