Boys n girls, which recent so call high tech feature has practically made a modern racket more superior than say one that is manufactured 10 years ago? Just an analogy, If I give Li dan, Lee Chong Wei each the original carbonex 21, a 20 year old racket, will each be able to perform equally best with their current racket? What do you think?And if you notice any leap in shuttlecock technology, pls share with me here. Because in my eyes, the main stream shuttlecocks look exactly identical to the one i used when I first picked up badminton which is a long long time ago. I expect some sort nanotechnology or titanium coating in the shuttles since these tech seem to be in trend.The same also true for strings, I say more than 50% tht is available presently came to the Market more than 5 or 6 years ago. Pls educate me, thanks a lot.
