Seeing that the double strikes are a soft-blow phenomenon, this problem could be alleviated by use of Crescendo front rail punchings. Crecendo punchings are made of a firm and resilient felt, which results in the same dip and aftertouch on a light blow as on a heavy blow. You essentially get almost 1 mm "extra" keystroke on a soft blow as compared to using the standard front rail punchings. With proper aftertouch and the jack escaping from the hammer butt, the hammer will check and not bobble.
