I think the lack of extended length players racquets available nowadays is a pity for the shorter amateur players, as you get a choice of a control racquet or an extended Babolat (The Pure Storm Tour extended looks interesting, but the string bed still feels a bit lively on the regular one). I would really like to try hitting with an extended Prestige or a POG longbody.
Yes, shorter guys get a serve boost. I've read a few articles stating that extended rackets have the most impact on serving. Chang was one of the first short guys to improve his serve with x-racket. Personally, I am not a fan but could see giving them another shot as I'm a hair under 5'10".
Ferrer also uses that goofy 2 HBH grip with his hands about 2-3" apart. I am sure the extended length helps compensate for his lack of reach on his backhand.
