Great video! The explanations of the basics and how to know when to throw back hand or forehand was great. Would really like to see a video on advanced one handed tying. e.g. Do you reposition on a forehand between your third and forth finger or keep it wrapped all the way around your fifth finger as you guide the knot down? Does this differ if you are securing pericardium with silk, tying a purse string on the aorta with proline, or tying a coronary with hair like monofilament? Details please!
