re: Golf Club question/recommendations/ advice needed.

I think it depends on how much he needs them extended due to swingweight. 0.5" will probably add 2-3 points, which may be manageable, but a full inch would be more like 5 or 6. Not many people can play well with a club at D8.

Since your clubs are 10 years old, I'd wager to bet that they aren't worth the extra $100 plus dollars to have them extended. I would look for a set of used custom clubs on ebay that are the right length with a normal swingweight and buy those. Changing the lie angle and loft a couple of degrees is pretty cheap and easy so I wouldn't worry about that so much
