For this sort of situation, I'd always avoid any generic advice that isn't a "how to". "It depends on the team" really is the only generic info I'd share, since you still have to consider your situation. The more professional and emotionally mature your team members are, the more I'd share. If a huge deal fails, juniors can be badly affected and will pull down morale, without much upside. On the other hand, experienced colleagues can catch early mistakes that could cost a lot more later. Try to mentally simulate people in multiple situations and it'll be a lot clearer for you.
