(Raining all these days.... so have more time left to report my findings) Here are some of results from my experiements with my home made power pads: 1. Decreased or eliminated the initial board or stiff feeling for poly hybrid, which is very natural for the first couple hours or sessions. 2. Made string bed more live, i.e. increased sweet spot, or more elastic. 3. Reduced injury risks for poly hybrid. 4. Can gain more control via increasing tension without stiff string bed. 5. A little bit more power, however cann't quantify the increases. 6. No effect on tension maintenence. 7. Possiblely more spin due to more pocketing effect. I use POG mid, Gosen Polylon 17, Gosen OG Sheep 16 for this experiment. My own power pads are made of used window shield wipe rubber blade refill, which are very elastic than other materials and I believe that acting like woofer system for the string bed. Before applying power pads, I strung POG at 54 lbs, and for the first couple of hours the string bed are quite stiff and have board feel. After 1 or 2 sessions, the board feeling will go away, which is normal for almost poly strings. Higher tensions, such as 56, 58 lbs, the board feeling are terrible, just like hitting wall, which normally will cause injuries. Afer applying my power pads, I have increaed tension starting from 54 lbs to 56, 58 and finally 60 lbs while the initial board feeling disappeared. Until 62 lbs, I started to feel the stiffness coming back. 60 lbs is the normal tension I used for synthetic gut strings. So that's very significant increases in tension, i.e. I don't need go down 5 to 10% for poly anymore. I have really enjoyed with power pads and high tension setup. If you use different material for power pads, your mileage may vary since the elasticity should play a great role. Now I guess I can understand why Peter and other Pros, who use power pads, can go such high tensions... PS: I use Laserfibre ECO with fixed clamps.
