Thanks for the video Moss. It nice to see other climbers techniques in action and can be very helpful in developing skills.
I noticed you are using your Pantin and your free foot together. This is a great idea and would surely help to prevent an oversized right leg. May I offer the following suggestion....Try using the drt rope walker set-up

pioneered by Beranek, it may be a little quicker and would require a little more gear but is much more efficient. I made my own using a used Petzl basic, some webbing and a bulk bungee from onrope1.
