Tuning and boosting on a DIY basis is to say the least, contraversial. Many national governing bodies will follow the guidelines laid down by the ITTF so if you want to play in competitions and events organised by your national governing body you'd be well advised to check if tuning and boosting is legal for those events. If you play in your own basement or friends, you should be able to choose whether you do or don't. One of the bug bears is that the question is asked, why are manufactures allowed to tune and boost but players aren't. What's the difference. Rubbers cost a fortune, so why not allow tuning and boosting to improve their performance and extend the lifespan of your rubbres, isnt' that the "green" and "responsible" thing to do, keep using something as long as you can? Well I don't want to get in to that argument. You pays your money and takes your choice. However, if you are curious to know whether tuning and boosting can improve a rubbers performance, maybe buy a cheap sheet and see if you can tune it to perform as well as an expensive sheet, then this type of video would be for you.
