I'm not remotely qualified to give you constructive feedback but I have looked at lots of videos on this board and the SSC one for my own purposes and I just wanted to say I thought they looked really good, like really good. Everything just seemed 'right' and as if it was easy (I'm sure they weren't but it's always said you can tell you're good at something if you make it look easy). Frankly I felt bloody jealous!
So take that with a pinch of salt because I may be way off but thought you might like to know!
I would be interested as to whether anyone feels you need to stand up a bit to complete the rep. That's more for my own interest because I'm a bit confused as to how much one really has to stand up and whether there should be more bending forward at the ankles to get the weight over the mid foot, views seem to vary.
