Lefty fitting

My son is 13 (5-1HT,90lbs) and has 6.4 handicap currently .  Current clubs tour series uskids with steel shafts, burner driver,3w and hybrid.  Looking to get him a real set for Christmas and need some advice as to moving forward. We are located in Jackson Mississippi and need a full selection of left handed clubs to sample from irons to woods to wedges.  Please advise. Thank you. 

I'm 16, and have a handicap of 2. Just purchased brand new irons in August around my birthday. See if he can hit the ap2's or 712cb's. Great clubs, a little expensive but if it's not worth it i would recommend hitting the taylormade cb's or mb's.  But if you are looking for kind of cheap and great for that age try the 2.0's or CG16's.
