Been looking at the older radicals and some other low power racquets. I like the specs of these clubs, stability, plow through, etc. My question is about how much more power can I expect to get by lead and higher powered strings to bring any racquet from LOW to low-medium or even medium? I think I read somewhere I can expect to generate about 10% from other than the racquet itself. Do any of you guys have ideas or experience with Radicles or any other clubs after working on them? Thanks in advance.
