Unless the water pump draws A LOT of power I'd go for the 25%.
I had 25% or 27% U/D pullies on two of my previous cars which were automatics (85 Vette & 95 Z28). The only time I had any problems were if I was stopped for a while with the blower motor on high, fog & headlights on, rear window defrost on. I'd just shift into neutral to raise the RPM's up if I noticed the voltmeter starting to drop.
