[QUOTE="brownedout, post: 979093, member: 30910"] I responded to your power zone question to LM rep earlier, and hoped to get into end range motion area also, and didn't have time, I needed to leave for rest of day. I hadn't even known about this guestion yet, it is best to address your area(s) of concern working through this example.
