Definitely not because the bats they get aren't good enough. I've never had one pro say a bat didn't ping. It's a case of what they're used to. Handle flex, handle size and pressing (sometimes it felt hard, or too soft) were the main reasons I had agents complaining. They're hard things to rectify without a pro spending a day with the batmaker. Which is impossible if your pro is Australian and your factories are in India/England
And leading on from that question, why don't the companies actually make, for sale, the EXACT bats that their sponsored players choose to use?
Because we'd have had a range of 40 bats, each varying heights, weights, profiles, handle shapes.Even then they're not gonna be the same. You can't clone willow.
