As a rookie, Im glad to hear the different perspectives on this. I've called a few techs this season, and have wondered about it.
One of my mentors told me early on that one of the hardest things for a rookie to learn is when to call the T. I haven't really had this problem much, with one exception, and began to wonder if I needed to learn when NOT to call it.
Your comments and feedback helped me to think Im on the right track...
