I noticed there are a couple versions of the energy saver a/s tires. One is heavier and has a higher speed rating/load capacity. Does anyone know if there's anything different about the Crr of these two tires, or is one just a smaller/lighter version?

Yes, just a difference in load rating (construction). You want the T rated tire for best FE. If you drive aggressively and or drive on very rough roads or gravel I would go with the H rated tire because it should be a little more robust.
