69 widetrack, after reading your response I see the kid's point, and have dealt with that too. It's very frustrating. One thing I noticed about guys who don't want to share their knowledge or are hard headed, is that when they're stuck in that mode for far too long they end up lagging behind the technological changes in terms of newer and better approaches. I've seen a few guys that were clueless on how to address flexible substrates cause when those new industry standards came out they already thought they knew everything. My stance is that if you're gonna have that "I know everything" attitude show us your work or shut up!
It's always best to make aware that you are not perfect, you are willing to learn more, and that the learning never stops.
