But the diameter is wider than the green punching pictured next to it, which, I would think, would cancel out any reduction in mass. I don't doubt that the punchings are better, but it's hard to believe the taper helps any if they're wider than the plain ol' green ones. I imagine it's just the more firmly-packed felt (denser), as mentioned earlier in the article, that makes the key hit bottom with a more positive (less squishy) stop. --David Nereson, RPT
