I would like to put together set of golf clubs for my two 8th graders (a boy and a girl).  My thought is to start with a set that has a driver, FW, HB, 7,9,PW and a putter.  My thought is to start with this and then as they grow into the game, I can reshaft and add clubs to the set.

Do I follow the standard wrist to floor distance to determine club length, or is there some other standard?

Any suggestions on club heads and shafts?
