If you fit Roubaix tyres they'll feel great but probably wont be as reliable on bad roads. Lighter tyres tend to be thinner and softer tyres tend to cut up. If you're riding for 8hrs+ I'd suggest a compromise that means you don't have to carry more than a couple of tubes.
I thought the Roubaix tyres were meant for bad cobblestone roads!
The Conti 4 Seasons haven't punctured since I put them on, roughly 6 months ago, and they're only 250g.
Although I do tend to run tyres at a lower pressure - about 60-70/70-80 front/back, which could be part of why they haven't punctured.
I always have a puncture repair kit and spare tube with me, but still working upto 8hr rides.
