Interestingly enough, our association stressed that very point this year at one of our meetings. We have 23 newly certified members and the point was made clearly - don't overcall the obvious. A simple closed fist out signal on a play that was not close. No signal for an obvious safe call - at any base. If no throw is made, than no call is necessary. As " veterans ", we need to help the rookies understand this concept. Take them aside and explain the theory.
If you save the big bang for the big play, it has much more impact and doesn't look like showboating. We all want that third out call with bases loaded in the bottom of a one run game to mean something special - ring it out.
And then get out of Dodge!
Just my humble opinion.
