Btw. you should make it ... free.
Do you sell your kendamas for free? We'd love to know where you get your photocopying done for free. And where you buy your printer ink and high-grade paper for free.

The fees we charge are pretty small really, and unsuccessful entrants at the higher grades get a refund. Imagine this: someone takes a Dan exam, but fails on the very last trick. They get a refund, so they've only paid £2, but the exam could have taken half an hour! How much is
your time worth?
Also, if something is free it can be perceived to have no "worth". These are serious exams, and the award of a certificate is meant to be a meaningful recognition of effort. Someone who really
wants to do well at these gradings has to put in a lot of time and effort into their skills and practice. To such a person the fee is of little consequence - the achievement of a Dan certificate is a great feeling.
On your blog you wrote that the JKA gradings are free. Actually the JKA
do normally charge for gradings, but our friends at Munich were kind enough to waive this charge for us, since we (as European-based players) would not also be getting the other benefits of JKA membership. This BKA initiative was created so that players will have more than just one chance a year to acheive a grading.
Also, endeavours that take time, planning and outlay are rarely free. The gradings are designed to bring an extra factor into the kendama scene - hopefully one that players will want to strive to achieve. Ultimately we hope it will help to build the scene even more. Which should mean that
you will sell more kendamas!

Btw. you should make it European from the beggining.
Well of course we want this to go across Europe. Very glad to hear in your blog that you want to work "hard to be the first to implement them." Watch this space!
Hopefully this post does not come across as defensive - we're just trying to explain the thought processes, and hopefully make things clearer (and more exciting?!) to everyone.
