With your own extensive willow supply you can choose the best for your own bats and flog the rest to India
Do you honestly believe that... the Indian market is probably a hell of a lot more picky than we are when it comes to grading. The fact companies over here can even get away with selling "performance" graded willow says enough.
Whilst everyone has their own opinion (this thread clearly shows that!), until an industry standard for willow grading comes into play then grading is simply a way of marketing a product.
Due to not making bats personally the process is a lot simpler for me. I simply trust my batmaker when it comes to grading and leave it with them - if I order a "Grade X" bat then whatever arrives is "Grade X".
