Consensus - Clean Block Signal?

[rfp]

I know the reasons not to make the clean block signal -- it isn't approved (to my knowledge), it makes your partner look bad if he comes up with a foul -- but I've seen many good senior officials use it anyway. It seems to me officials use it to signal to everyone that they saw the play clearly - and have nothing, much like the use of the "tipped" signal when a ball is deflected to the backcourt by a defensive player. What's the consensus of the forum? Use it or do nothing?
