[CAUT] Downbearing Error

Hi folks

Looking for advice as to how to go about correcting a downbearing 
error.  There is too much downbearing.  The thought is to remove bridge 
pins ... say five unisons at a time.... shave down the bridge top string 
up again.  This will necessitate plugging bridge pin holes and 
redrilling as I need to come down probably 2-3 mm in places. 

The high spot of string deflection is the leading edge of the bridge.  
My question is whether its best to leave the back edge at the height it 
is and angle the bridge surface down more towards the leading edge... or 
should I remove equally across the entire surface of the bridge ?... or 
is there another way of going about this.

I cant change anything about the plate height in this instance. I have 
to accomplish this by altering the bridge.  Back lengths are too long to 
raise them enough by half rounds... and that would look wrong here anyways.

Thanks for any input.


Cheers
RicB
