I thought narrower was more aeroz on the front, especially if the rim width at the brake track is less than 26mm*.Whether the aero gains will negate the increase in rolling resistance will depend on your speed and the surface.
Normally I would agree but they're very wide rims so thought perhaps getting 'closer to rim width' might be faster than 'skinnier than rim width'. At 30mph I would think aero is more important than Crr (especially on the front, I'll leave the 25mm on the rear).

*assuming actual tyre widths, rather than nominal
