I don’t have a set, but from testing, they feel like butter on a clean hit. Get about 175-180 on the carry for a 7 iron (122mph ball speed avg). They look phenomenal. I actually went with the P730s in the end and will probably combo my long irons with P790s. The P730s are just a dart. The P770s just didn’t quite have enough spin but fairly close. Hope this helps!
