I would doubt the weight of that machine + chains could do much damage to paved surfaces unless you put the loader against a snow bank and deliberately spun the wheels.
but I also want and need better traction the next snow (no matter how many years from now) than I had for this recent snow. How much better are the 2 link than the 4? Or would I have noticeable improvement with the 4 link? Is there a clear choice here?

2 link put twice as much chain on the ground as 4 link. They ride smoother, last longer, deliver more traction and cost more.
Also when you get into fail modes... I can loose a cross chain on a 2 link and have much less compromised traction than with a 4 link setup.
Looks like a set of 4 vs 2 link is about $80 different according to tirechain.com. $80 for increased traction, chain life and smoother ride?
For my applications its an easy choice 2 link.
