Tying knots Pro knot vs Parnell

Someone asked me the benefits of different knots so I am comparing the Pro and Parnell knots. Some use the Pro knot in tight locations which are difficult for the Parnell. This method makes the Parnell a piece of cake so I use the Parnell exclusively.
Check out the rubber band vibration dampener in bottom of the racket. It deadens the vibrations a lot compared to rubber bands that are tied into the frame.
