Hi Mattias, If you build a set of 716 AP2 irons with Aerotech i95 S flex shafts at standard length, with a stock grip at standard wraps, it will build about 2-3 swingweights light. The Recoil 95 will build about 1 swingweight light. You can add a grip such as a Muli compound and it will add one swingweight so on the Recoils, we can easily get to D2 when using that grip and using standard heads. On the Aerotechs, we would probably need to use a heavier head to get to D2. Either way, your pro will need to request that swingweight when placing the order.
