Wheelbuilding / Wheel Building / Wheel build help

Crosspost from Polo thread.

I'm having a new polo wheelset built, and my parameters are as follows.
26", 36 holes.
Strength (specifically for side impacts).
As small gaps as possible to stop balls going through.

So i've come up on a variation of 3x and crow's foot, and it meets the small gaps, but I'm not sure how strong it will be, or if it is even a good idea. Any thoughts?

This looks potentially interesting, a cross between 3x and crow's foot.

I don't know much about wheelbuilding, but it certainly has smaller gaps, but would it have the strength of 3x? I guess having two spokes from the same side of the flange crossing so close to the hub isn't a good thing though.

Normal 3x
