I myself would go narrow. The harsh ride may talk about is an opinion IMO.
I've had a few others say that a Cannondale CAD3 is too harsh a ride to go long distance. Many of them doing 30 miles on smooth surface trail rides. But I took my CAD 3 on many many trainng rides and about 10 centuries with no problems while these riders claim to lose fillings in their teeth on newer smoother Cannondales.
Heck, if anything, switch back to the wider tires once they wear out. You sohuld have formed your own opinion by then and a tire is what, $30.
