Yamaha hammers

I am actually amazed that I read so many mails about Yamaha hammers 
being so hard.
Could it be that Yamaha's prepared for the US have harder hammers than 
the ones prepared for Europe?
II remember a time when there were stories here (in Europe) about US 
piano's sounding completely different but I have no real knowledge 
about that.
Anyway, I do remember the early Yamaha's here in Holland, and they were 
hard indeed, like granite. That all changed in the seventies and they 
even became totally soft at the introduction of the new C series in 
1995 but that had to do with the fact that the our Japanese colleagues 
started to use pneumatic voicing tools. They simply overdid it.
Today, it seems as if the English made Yamaha's are too hard and the 
Nippon Gakki ones are back to a pleasant normal.
The CFIII-S has Wurzen felt, which makes all the difference in tone 
building from the start.

Friendly greetings,

btw, we sell Japanese needles that only break if you have no experience 
with voicing.
