Yah, I rotate a lot of stuff between my Driver and 5i: Callaway X 3w, Cleveland 4w, Titleist 21 909H, Nickent 3i Ironwood hybrid, this funky early metal 5w with a steel shaft.
Totally whimsical, 3w about 220, I hit all about the rest about the same distance (about 175-195).
That said, when I finally got my wedge gaps down, game became a lot more steady:
Mizuno JPX 50 Supposed to be more forgiving, which implies less of a shot maker. Cast, not forged....
