Heard another interesting tidbit in the video linked below. Skip to around the 4:45 Mark and you’ll hear Paul describe how he uses his shoulder to get over the string, at least when descending. Thought it might be of interest to some around here.
It seems the shoulder pushes or pulls the forearm to position the wrist to reciprocate over the correct string, so he needs “shoulder push” and “shoulder pull.”
This is wat Martin Miller also does and what i am practicing a lot lately.
In fact it is stringtracking from the shoulder.
