I'm running 160s on my "road" bike too, but at ~77kg. I think 140 on the back would be better, it's a bit skid-happy when it's wet/loose/off road and that's with 35c tyres...
That's a good point - going from rim braking all my life to discs I'll probably let loose the tyres way before I need to worry about the discs :S
