Terry, A few quick thoughts/questions - How much aftertouch are you using (and how are you measuring it)? Is there ANY chance this is one of those with the growing action brackets which will change leverages? 9.5-10.5mm dip is good, including about .050 aftertouch. 10mm is best in most pianos, even up to 11 can be used, but it tends to feel funny, and will probably cause most sharps to bury. How tall are the sharps? There is nothing inherently wrong with 1.5" blow, except the loss of power. It is just an indicator of unusual design or condition, and should at least make you suspicious (as you are). In fact, it will probably lower the downweight. Force the dip as large as you feel comfortable with, and there you go. You are limited by the design, but it's worth some exploration to make sure that the problem IS the design. Bob Davis
