action ratios

[Stéphane Collin]

Hi Roger.

Thanks for your input.
Up till now, I deep needled shoulders to get a good sound at forte level, with enough root frequency to make the overall sound warm enough, and to avoid distortions.  I'm afraid that deep needling more than what I do would compromise power and colour shades, dulling the whole dynamic range of the hammer.  I tried to cure my problem by diminishing the hammer blow, but I found that hammer blow is not THAT influent on the dynamic range.  I couldn't feel the difference in dynamic shades between two settings of hamer blow different of up to 5 mm.
Any further thoughts ?

Stéphane Collin.
