I've been using 25's for quite awhile (195-205 lbs.) and I like 'em. I actually notice less rolling resistance with 25's than most 23's, but it might be the nature of the tires - Vred Fortezzas pumped to 128R/118F PSI.
I think for the slight extra weight of 10-20 gm. per, 25's are a definitely good option. Better at handling rough road conditions than 23's.
