Mate, genuine response, your question does not follow from my quote.
I was getting at the bat issue when I asked. The answer is yes, they're all made of wood. But do you use them? Have you used the older bats vs the modern ones? I've played for like 20 years with varying levels of failure. I've personally always used Slazenger bats because when I was a kid the Waugh brothers were my favourite players, and the store my parents bought my first real English willow bat from didn't have any GM bats so I got a V100. From there I just always liked the feel of the Slazenger stuff. My current bat is a V600 I got probably 12 years ago, it was like $350. 2lb 8oz, it's probably 3 inches thick at the middle and they used a hollow core to reduce weight, otherwise the equivalent V800 bats added about 4-5 ounces without the hollow core.
My best batsman just got a new Gray Nicholls. It's exactly the same weight as my bat, no hollow core, immaculate pick up...except it's over 6 inches thick at the middle and pretty much as thick as the middle of my bat at the edges. It's ridiculous, and it cost 100 bucks less than mine did back in the day. What they do with willow these days is mind blowing compared to even 2005, let alone the 90s.
So, yes, they are all made of wood. But they are completely different pieces of kit. It's like comparing a Civil War musket with an M16....
