Report Super-Lightweight Drivers That Don't Hit the Ball as Far in Clubs, Grips, Shafts, Fitting April 14, 2016 2 minutes ago, iacas said: I know it's so weird to me though were talking grams not 5 pounds vs 20 pounds dropping from a 2 story building and figuring which one will do more damage. I will say that a 2 pound ball dropped into a cement object would probably deliver more direct energy vs a 5 pound metal can,at least that's what I can see in my mind. Again your just using a play on words it's trivial an irrelevant. 5 pound can,bucket etc.. The point being it's large hollow and weighs more than the compact lighter yet dense 2 pound lead ball. Ill take the homer bucket falling on me all day vs that lead ball,but in a way that's irrelevant were talking golf ball x mass and energy transfer just an idea. I'm not saying iv'e tested this or have seen this as absolute. .
