  My Dad was a dealer till 1981 we were alkways told 48mm /10mm dip on  grand 
& 46 upright. So if they've changed it that means the've changed  geometry 
over time to do what? Carry more hammer weight perhaps

You know  Dale... seeings how this is a Yamaha... I didnt stop to think 
to check a  few of the things you mention below. But you did hit on 
something I didnt  mention... tho I didnt measure it, I did get the 
impression this was a bit  heavier then usual Yamaha.  Couldnt be 
centerpin friction tho... as  these are newly protek't and nice and 
free... too free for my likeing..  grin.. but thats another story.

I'll look at some of these basic  <<Stanwood>> parameters next time I go 
down in a couple  weeks... off list Jon Page also suggested I double 
check to see if anyone  has dinked around with shimming the stack.

46 mm blow is the figure we  were given at the Acadamy.  47 was said to 
be like.... ok if you  wanted to get less aftertouch... 48 was supposed 
to be no no...

But  what suprised me was that I couldnt adjust to 50 mm... not that I 
should  want to... but there is supposed to be around 5 mm between the 
shank and  rest cushion.

Cheers and thanks for the  thoughts
