I remember Mickelson saying that the advent of the Pro V1 automatically added 30 yards to his driver because he could swing flat out knowing that the side spin would be far less than a wound balata ball and he would be straighter (I am not joking!). The technology in the ball where it spins slower off the driver than it does off a wedge is the real game changer. -Mahoni
So agree. I cannot speak to the clubs you compared but I still routinely play last generation 3 piece wound (Maxfli HT100') and I play Pro V1 X. Big difference is in how the wind effects one and not so much of the other. How one rolls truer than the other on the green. The Pro V is flat out better in everything except feel. And those HT's were sort of in between Tour 100 balata and the Pro V in tech.
Great thing these days is you can pick & choose your comfort of tech and derive a definition of the game to some extent. When I want to have fun with the wind, it's the HT's, when I want to score, Pro V1 X. I want to max the tee shot, B300S.
I've always found the HT-100 to be a superior wind ball. The shot I remember the most was hitting a PW with a 20mph side wind. I hit the ball at the left edge of the green expecting some drift, and it landed at the left edge of the green. Didn't so much as twitch.
Now curving due to draws and fades? Hell yeah. My first time putting one of those in play after a couple years, I had to laugh at the little draws and fades I'd get almost randomly.
To me, that's the biggest thing about the ball. It's straighter. It's not really particularly longer, other than the effects of lower spin on the longer clubs.

I'm guessing that the Mac 9-iron is 45* versus 42* for the Mizzy but I wouldn't have thought that would account for 30 yards. The Macs have Tourney Taper #1 Stiff shafts, Mizzys have S300s...the Macs feel slightly heavier but I've no real idea on comparative swingweights.
It's quite possible the 9 iron on those VIP Limiteds could be as weak as 48°. The 52° PW still existed into the late 60s and early 70s, and your set, um, I mean your friend's set (LOL), are very much an early 70s club.
They could be anywhere between that and the 46° 9 iron seen in the FG-17s, which were in 1981-83.
Beyond that, it could be all sorts of things involved. Shafts, different CG placement, varying static or swing weight, mahonie studliness....
As for grooves, square grooves didn't come about largely until the Eye2 in 1982. They're probably V grooves. Your Mizunos probably also have V grooves, there are a few stories around about how Mizuno never went to square grooves in their blades. Maybe even all irons. <shrug>
