Thanks for the very information replies! I am really learning a lot from asking questions and reading previous posts here about club making as I never really got into it. Back in Australia, I had friends who worked at the proshop so I never bother. But now I am in Japan, the golf shop charge a considerable amount for doing something so simple. e.g. a grip change woudl be about $15 with the standard tour velvets. Getting shaft cut would mean an extra $15 for each club as well. So all in all, I would have had to pay around $200 to get the whole set cut and regripped. I should consider opening up a golf shop here to do all these stuff at a much cheaper rate....

As for fattening the grip, I want the grip to be slightly fatter as I have noticed that I am able to relax my hands more. I will take a look at that website to see how many layers of tape I should use.

Again, thanks.
