Are you thinking about moving to the 699 Pro in 8-PW? or more utility vs hybrid?
I’d say if you are launching the 5 iron well with the utility, stick with that, and only move into a hybrid if you want more height out of your club…
I play an 18 degree hybrid and a 22 degree 699u, and they are great setup for me, as if I need to keep something low, I hit the utility and if I need to hit it high, I hit the hybrid.
They both fill roles as “position” clubs (I’m less worried about how they land on greens, though I can get the hybrid to stop) and are primarily used to get my back into play and set up a 2nd or 3rd shot.
The differences between the Utility and the 699 are minimal… I think it’s slight more offset.
