Personally , I like using the spread arms in the not closely guarded situation to say that I am aware of the rule, but at this point in time it is not applicable. I try not to do it in HS games, but I have caught myself using it.

I can't agree with your view on the travel signal on the spot throw in violation. By using the travel signal, we send the message that traveling rules are in effect during a spot throw in. In that case, you need to be very verbal about the violation that you are calling.

As for the "foul tip" signal on a clean block, I was taught never to use it. Here is the main reason: Lead official sees the shot attempt and is giving the "foul tip" signal as the trail or slot blows the whistle and calls a foul on the defender. Now you have a defensive coach screaming that the lead had a clean block, why is the other guy calling a foul?!? It just avoids problems to not give any signal in this case.
