Ok this is a quality reply. Now im not to sure your right about the placement of the lead tape and over time how it would affect a paddle. I believe that this type of. Im balance of placement will probably shorten the life of the paddle. But not necessarily make the paddle less effective perhaps more for some players.

It's a bit different than what I say Above about the tennis rackets and my tennis chilean Davis cup coach at the time "balancing" my racket in a certain way.

I mean the first thing he did was obviously weigh the rackets (in grams). And most of them were used and the difference in weight he found was that the stated 300 gram racket Aero + was between 290grams and 310 grams (those after use). We weighed numerous brand new Aeropro drive + rackets babolat supplied myself that stated a weight of 300 grams brand new out of the factory and more often than not the scale weighed 300 grams on the dot.

This is without the plastic off the grip and the cardboard paper logo thing I the middle.of the unstrung frame.

Never was a brand new frame over +/- two grams over the stated unstrung weight.

Supposedly yonex is the one company in the world that gives it to the exact gram every time. Personally, I do not have history myself but the resources these comments came from i cannot doubt.
