Again, no real proof that bigger is better.....commentators say a lot of things! 😆 The Pro's I've spoken to about it say it's more a visual/confidence thing, rather than a performance benefit. Surely modern Pro's hit more sixes than us clubbies/players of old as they're better, more skilled, stonger and practice hitting all the time?
In terms of brands not making bats that can't be replicated, don't they do this? 'Players Editions', are very different to the usual ots bats. It's also why we now see narrowing, dryer willow, light handles and grips, thin toes/shoulders etc. So brands can make 'big bats' at light weights.
