As you gain experience you can learn to adjust in either direction, even though there is an adjustment period. However, I had adjusted my keys so they were weighted heavy, for me it was eaier to go from heavy to light. These days I've lightened them back up a bit since I'm not playing any heavy action Steinways any time soon ( my teachers Steinway many years ago was quite on the heavy side).
So maybe German pianos in general are heavy? I didn't know one could adjust the action. Will ask my teacher if he can make my piano's action better. Will safe a bit for an hour tuning and an hour of checking the hamers and such. Well worth it; investment.Thanks for your comment David!
