True, and in some cases you get what pay. I read people saying the cheaper low grade bats or SportDirect bats are over pressed for resilience rather than higher end softer pressed bats that instantly respond, but don't last as long. Similar for younger wide grain bats. I am old enough to remember most bats in the 80/90s needing lots of knocking and playing in before they would soften and play well. We would buy one bat and cherish it and it would be at its best just before it broke.
These days we can buy cheaper bats and just change them over. A guy at my club says he just buys the cheapest Puma off the shelf and uses it without knocking for the season. He's crazy not knocking it in at least, but his chances of buying such a bat are more likely. The other part of his logic is sound, that its his technique that makes runs, not the bat itself, but i'd personally like a bat that has some ping.
I actually subscribe to the logic that you just keep patiently knocking and netting until it fires. The difference is performance being a property of the pressing, handle and willow quaility. For the sake of the exercise just keep the answers coming until we reach an answer that is as close to best practice as possible. Is there a DYI fix for a over pressed plank?
