Ralph, just for the record, I'm not trying to suggest a cadence. The ideal cadence for each of us is going to be different for many reasons and one's own ideal cadence will more likely than not change over time. I just wanted to address the common misconception I saw pop up here that height/leg length is directly tied to cadence/stride length. There may be some small correlation but there are much more significant factors.
As I think John is kind of touching on, any difference in severity of the problem is very likely related to the degree of length discrepancy, as well as other biomechanical factors.
