[CAUT] Moving wippen rail

[David Love]

I see.  The net change in leverage with a wippen rail move of a few
millimeters may not be that significant to show up as an easily measurable
change in the dip/blow specs.

I think the issue here is the discrepencies between the weight change and
lack of change of dip and blow. There seems to be a denial that there is any
change because the dip and blow ratio is the same. What will change is the
aftertouch.

I guess the bottom line is your bottom line.  If you shim the wippen rail
out and the UW and DW drop then what does it really matter whether the 
explanation is vectors or leverage?
