while I am well aware of golf clubs, sole grinds, groove types, etc...

the concept of altering the wedge MOI and COG with weight ports is interesting...

BUT!!

without specific details, it's hard to guesstimate how much effect this really has...

Let's do a little math. Based on the pictures, the diameter of each port is no more than .75 centimeter. It's probably even smaller, but let's go with .75 cm. As for depth, we'll even go a full cm. Therefore, the volume of each port is:

PI * r^2 * L = pi * (.75/2)^2 * 1.0 = ~.44 cm^3

Assuming that the club head is made of steel and that the inserted weights are tungsten, the mass removed from the clubhead is as follows:

density of steel: 7.85 g/cm^3

mass of removed steel: 7.85 g/cm^3 * .44 cm^3 = ~3.45 g

density of tungsten: 19.25 g/cm^3

mass of inserted tungsten: 19.25 g/cm^3 * .44 cm^3 = ~8.47 g

net increase in mass: 8.47g - 3.45 g = ~5 g each

Since there are two ports, there is a net increase of ~10 g.

If you've ever held a 10 g object before, you'll know that you can barely feel it in your hands let alone on a clubhead that typically has a mass of ~300g, but let's continue on and do some rough MOI calculations.

Assuming that the reference axis of rotation is exactly in the middle of the two weight inserts, let's say that each weight is 3 cm from the reference axis. For the sake of simplicity, we'll treat the weights as a point mass and calculate the MOI as:

I = m * d^2

where m = mass and d=distance from reference axis

So, the MOI for the removed steel is:

I = 3.45 g * (3 cm)^2 = ~31 g-cm^2

Since there are two ports, the total MOI of the removed steel is ~62 g-cm^2.

Note: Yes, MOI is additive.

The MOI for the added tungsten insert is:

I = 8.47 g * (3 cm)^2 = ~76.23 g-cm^2

The total MOI for both tungsten inserts is: ~152 g-cm^2.

So the additional MOI due to the tungsten inserts is ~90 g-cm^2.

Now, what's the significance of a 90 g-cm^2 increase in MOI? I have no idea. Considering that the MOI of most clubs is on the order of 2000 - 5000 g-cm^2, I would guess that this increase in MOI is insignificant to the forgiveness of a wedge.
