This video is one of my favorites. It is not quite up to date (it features the later version of the T7), however, it is informative and contains a lot of solid information, as well as some good humor.
I have found that I continue to learn from well done material, written and video. I hope you enjoy this as much as I do.

ps I realize I have posted this video before. I am not going completely senile. We have an ever changing group of new members and guests who might not have seen earlier posts. I also think some of the regulars might learn a few new tricks.
