It isn't as simple as F=MA gents, go buy yourself a very heavy mahogany cricket bat with a 20mm spine and see how it compares. That said, when pro players are hitting it out of stadiums with a 70mm spine bat, making them use one with a 67mm spine isn't going to stop them clearing the 65 yards to the boundary.
Does that mean halestorm will be discontinued next season?Majority of OZ team plays with these big bats.
From what i see in the test series - DW is playing with a big GN bat. Rest of them don't look that huge .. which other player are you referring to?
Imaging someone playing with 2lb 15oz - 45mm edges and 75 mm spine. Now if he wants to maintain the same shape and bring down edge/spine size but still want the same weight then the willow will need to have higher density.Does this mean low density clefts are going to get cheaper then ??
I think the check will be via a bat gauge which will have a straight line from the 40 mm edge to the 67 mm spine and the whole bat needs to pass through it. So as some are stating that next shape will be the spine height of 67 mm spread wide, is not going to pass the test. Similarly convex back profiles with 40 edge and 67 spine wouldn't pass either due to the straight line restriction from edge to spine peak.
I think you are right, which is a shame. From what I read there is 7mm for the curve on the face, 40mm on the edge and 60mm spine. Basically any remaining innovation will stop if you have a cut out to check the shape of the bat.
