I'm in the UK by the way. I've searched on the web, and it seems like the only way to do it is a DIY job, with people suggesting you should sand it down by yourself (with sandpaper I assume?) It seems to me like a very inaccurate way of doing it. I could easily make a mistake and mess up the shape of the grip. So I was wondering if I get it donw professionally, by someone/company with the right tools and skills. The racquet I want to reduce is the wilson pro staff 90 (2012-13 edition, my preferred grip size has been sold out, which is why I'm left with this option). Is it even possible to do reduce the grip size on this racquet?
