Well, I have a Yang-yang Nano Sensation 100 which is strung with BG65 25 pounds long time ago, and a Yonex Armortec 900 Power which is strung with BG66 25 pounds. I felt my Yang-yang Nano Sensation 100 which strung with BG65 has more solid feel compared to my AT900P which strung with BG66 when I hit the shuttlecock . Is it true that BG65 has more solid feel compared with BG66?
I think you're talking about the feel due to the shuttle digging into the string bed as you hit it. The BG65 has technically less repulsion due to the thickness of the string, which flexes/caves in more than the BG66 when the shuttle digs into the string bed, thus you get to feel the shuttle in the string bed longer than you can the BG66. Another explanation could be because the 25lbs of BG65 has loosened and you get to feel it cave in more than the newer BG66.
