pre-serve routines

[UW_Husky88]

I was wondering what you guys think of pre-serve routines. Do you think that they help at all? When I say pre-serve routines I'm talking about things like Sharapova's hair behind ears, Sampras' weird one bounce racket shake thing, etc. I think that in a way they help because I focus on my routine and sometimes don't think as much about missing on a big point, but I dunno. Do you think they're overrated?

I'm sure it helps, the serve is such a timing oriented shot, its good to get into a routine.
