Recommend going for a Titleist fitting. You can hit all the irons and can choose what is best for your game. Distance is not an indicator of what you shoot. Am 75 and can my driver farther, but am in a funk, just cannot score right now. Swing speed 93. Play T300 irons with AMT R300 shafts. Have a great fitter. Working with my hitting instructor right now. Another story. Think I need to hang with a psychologist. LOL. =) Bottom line, see a good fitter with years of experience.

Think I misread you post. For my age, I like the Prov1 and the left dot is definitely a winner, if you can find them.

Tour Speed is a potential option. My speed is also slow, but I find it a bit softer feel than the AVX and the price point is more attractive as well.

The best spin will be with a urethane tour level ball. Which one is best for you can be done by trial and error (buy a sleeve of each and take on course) or get a ball fitting. You can research the various balls online but outdoors will tell you if higher launch (the X) or a lower launch will roll further (the AVX) over the V. At your driver speed the lower spin left dot or dash don’t need to be considered until you decide if the V or X fits your window best. I’ve tried Velocity and it may be longer with long irons or fairways, but I don’t get enough spin to hold a firm green.
