Hello list,
Thought that I would seek comments on an action with high leverage.
Key dip is 10.5mm and blow distance is 41mm.
The touchweights are in the low 50's down and low 30's up.
Knuckle spread 16.5mm
Key ratio is 1.81 
Action spread is 113mm and is adjustable.
Any more dip will make the sharps about level with the naturals when depressed.
The feel of the samples are acceptable.
Seems that 41mm blow distance is short - but is it too short? Maybe some loss of power?
Is there a down side to this action?
Any corrective suggestions?
It is in the sampling - disassembled stage.
Thanks,
Gene
