Getting my dad a set of clubs for his birthday. Leaning toward the 5 and 7 wood Maltby KE4 TC Pro IST club pak. Deciding on shaft options. His average driver SS is 84 mph, his average 7 iron is 72 mph. He is unlikely to get any stronger from here as he has health issues, so keep that in mind. What shaft profile and flex would you suggest for him? Not sure if he is Senior or R flex. His tempo is average. Thanks.
