Bs 09: stiffness 3/5 head heaviness 3/5Bs 10: stiffness 5/5 head heaviness 3/5Which is easier to smash and handle?
Depends on whether you're able to flex that 5/5 stiffness. If you don't have the power then go for the less stiff shaft. I prefer BS10 because BS09 is a little flexy for me Why don't you go into a badminton shop and try both of them?
I think he is using Victor MX80. http://www.badzine.net/news/india-open-qf-%E2%80%93-shon-sends-gade-home-self-chen-to-london/19447/
Read alot of review on the net and BC, BS 10 sure is the more popular choice among all the other BS series. How true it is? Should really need to get a dummy set and try it for ourselves. Cant really decide for myself too >.>
