The community website ubercharged.net took some comments I posted and made it into a nice article and added tips from a medic I don't know of but who had some solid advice. In fact some of his advice is covered and expanded upon in the upcomming TF2 Tips and Tricks Volume 5 which was recorded a week ago and is now being edited. Look for it!
