Hi, Matt. If he’s just starting out, you might want to consider the Top Flite junior set. Golfworks has a very good price on it and it includes the bag. Here’s the link: http://www.golfworks.com/top-flite-xlj-boys-set-ages-9-13/p/TFK0003/
If you decide to build some clubs for him, the LTech is a great choice. I’d also recommend the LTech graphite shafts to keep the clubs as light as possible. The shafts for the irons are about 58 grams vs. 100 grams in the FST. Also, the FST is only in the A/R flex. The LTech is available in a softer flex (L, and LL) which I think would be more appropriate for him.
Hope this helps.
Thanks Michael. Thinking on it some more I might go with the L-Tech.
I saw the Top Flite set, but if I make the clubs for him I can always re-shaft them as he grows rather than buying a full set every time.
