Weight and other specs Looks as if I will need to go buy a scale for the 300-400g weight range. It will be fun playing with the racquet until I get the specs right. Then i will move on to the Ki 5 and Q Tour and get them right. If I add weight to improve power, is there any need to restring the racquet now to a lower string tension? It's a brand spanking new string job and the only local stringer charges $30 for multifilament.
