I DID read your poast, and I understood perfectly what you meant.
You spoke about velocity of strike, and you think this is different to velocity of repetitions - this is partially true, but they are still related to the raw ability af the finger itself.
I SAID about the precise and appropriate usage of the fingers to produce 'colours' and other 'musical' effects.
I also said, and this is where you're WRONG - that raw finger speed is the catalyst and facilitater of every bit of control that you apply to them..
It ain't the size of your tool, it's the way that you use it?
NO
I have an INCREDIBLE tool, and I use it marvelously.
You are satisfied with your mediocre tool, and as long as you do not get in enlarged, no matter how well you use it, you'll never produce the same effect.
