hello, Original Hamburg Steinway are the thinnest punching on earth (white 0.8 mm I guess) More stability and immediate response. I like the Yamaha ones (medium/thick but springy enough) On other I use Casmir punching, they are hard enough. I used once big whites one from Apsco (?) and had to change them, really too soft, regulation almost impossible even if ironed.
