Proper length for everyone is very important.  With proper length, flex, and weight you have the best chance of producing consistent shots.  I would certainly test clubs that are different lengths to determine which feels most comfortable and produces the best results. Find a local Titleist fitter and take the time to get what you need.

Thanks ill try to find a club fitter near me!!

Choking down is an option - sort of a feel thing for the player.  Playing with correct length makes on-center hits much more likely. I would prefer the player have the correct length of shaft so they do not have to choke down,but that is your preference.
