I was 'gifted' with a Z785 head a few weeks before the season came to a halt.
Sim, Sim Max, Cobra Radspeeds, Callaway Mavriks(all models), Cobra F9, Smt, Geek, and a few others have been played this season, all with great results.
But, and it is not out of 'honoring' a gift by a great friend, but that Z785 never left the bag once I built it. Except for hitting & cleaning.
And, I do think............'nuff said!!👍
I will add....the hosel is not as adjustable as you'll find on other heads, but it works good enough for what I want/need. Also, that damn tool....is quite different.
iirc, Kelly has one for sale quite reasonable.
