Before, by the way I look, I always believe Yonex Ti series have larger head frame (especially width) than cab series. Strung 3 Ti (1 Ti5, 2 Ti7 light) rackets the past several days. I usually strung all racket with 22*24 combo, therefore, the string tension should be a non-factor as they all the same. After strung them, I compared the head size with a cab10tour, and a cab20 (original, about 10+ yrs old), and I found all 3 Ti rackets are slightly wider than the cab20 (about <0.5cm). I don't think that's because I screw up the string process by putting "non enough" extra force on cross, since all 3 of them, are not any shorter (head frame only, measured from throat gromments to top gromments) than the cab20 or cab10 tour. Also did the comparison with some other non-yonex rackets, such as SOTX woven 4A, Yangyang Tactic 8500, etc. The results are the same: about same length, but Yonex Ti rackets are "wider". So, am I right about my previous assumption? Or, there might be structure factors involved, such as "widebody", etc?
