My general statement on this subject is:
Low level buys tend to become pointless too soon. Whatever you want to buy,
look out for the possible better equipment available at a higher level.
But now, at lvl 52, you are well past the inexpensive equipment, aren't you?
in dependance of your budget,
you have a choice of quality wedges from lvl 38 (ATV or Ping or Cleveland),
you have a choice of decent putters above 500 crs (and close to the level 55 Rossa),
you may buy the R11 clubs of level 31+, or just wait for the coveted lvl 59 G20s.
It may also be a good choice to select some cheap custom balls, B-ES or Tour-SD - real smashers against the Starter ball.
Anyway: Hit it straight, and have fun!
