the starter ser set work well but if you don't want to go that way I would pick up a mid range or slow fair way driver and a putter for each of you. a shark, buzz , cobra are some good choices and then what ever putter feels the best in your hand, look for 150 disc for your son. I have a 10 year old son and he plays most rounds with a 147 eclipse, 145 roc and a 157 wizard.
