It is great that you started this thread!!
I see that you set up the lead tape at 3&9 and higher in the frame. Which location you found to be more efficient?
What strings do you prefer and what lbs?
I put lead at 3&9 exactly as yours (or as in the Sampras' racquet pics from Greg Raven site) but just one layer and at 66lbs. Two or more layers of lead and it will be too powerful (which requires that I go higher in tension and my stringer doesn't to doing so
Also, how would you compare the KPS88 to PS85 feel-wise?
