I agree Climate is the prime difference affecting the two willows, but climate affects soil quality as well, particularly climate change.
I never claimed to be a willow expert, and happily defer to experts, such as growers. I put the tweet out on performance because it struck me as curious in light of perceived wisdom, and was hoping to spark a debate, not strike a nerve.
It's clear that English willow is superior and consistent. It is also clear that you can get very good Kashmir willow bats, but no consistent supply, and the majority of KW bats inferior to EW. But the question still holds, will that position be the same in 10 or 20 years?
The Pakistan government have begun the process of investing in the development of their sports industry, through education and infrastructure improvements. Bat making is part of that industry. The Indian economy we all know about, and it is pride more than economic value that drives them to improve their bat willow - they no longer want to be second best to the English. Is it possible? Or will EW forever be superior to KW no matter how much they try to overcome the climate differences? Is EW the finished article, or can it be improved?
