I realized most/ all of the professional players use strings such as bg66, bg65,bg80,bg85, bg68ti etc. The kind of strings that are cheaper and more available to us. Why dont they use the jp strings namely, bg66sharp, bg70 etc? Are the jp lousier compared to the normal strings that we use? (i know it must be some marketing way used by yonex to encourage the general public to buy this cheaper strings) But they should give the world class players the best. They are sponsored, so i think they will have access to it if they request for it? For world class players such as lindan, Taufik, FHF/CY? Why dont they use these?
