Grand piano /upright mods

Hi there,

I am new here, I just wondered has any one being thru the same experimental stage as I do.

I have been playing and conservatorium more than 30 years(6 years in cons.). I do performing on classical /story on charity basis not a traditional concert pianest.

I did this mod 15 years ago and still up to currnet date tried on my own children).

I add 16grams of lead weight to each key. The aim to strenghtening the finger. When comes to the stage-the concert grand-which is a lighter touch. Its a bit like "weight trainning/resistance traininig on piano.

Up to date, I have no regret at all. In old days, when I "played" an unknown heavier touch keys my finger /hands will worn out quicker. Now days, I hardly encountered any problem. Try play the revolutionary study in full speed-concert speed

I did the same trial(same grand) trained my own child since 5. And it seemed working......

Is there some one have done the similar experiment/mod.please let me know your opinion and any critics...

Thanks

come on you all piano virtuoso....there must be some one out there did this mod ....I need some feed back please....
