20s on the X too small?

I have been back and forth about whether to get 19" 132's, or 20" 87's this spring, and I was leaning heavily toward the 19's until driving the 4.8... the ride comfort, as I mentioned, was not bad, and the handling was awesome
I think they both look great - maybe the 20" 87s have the edge a little looks-wise - but I was a bit concerned about the low profile of the 20's, as much for pothole durability as for ride comfort. Now that I know the ride comfort is not a big difference, all that leaves is the durability... and I've actually never heard of anyone bending an OEM 20" X5 wheel on a pothole, so maybe that need not be much of a concern either.
I'm still not 100% sure which way to go here, and I've never actually driven a 4.4 sport with 19" wheels, so I think I'll have to give that a try before deciding.
