Rough roads for a 40-mile RR--What tires?

So I went out and pre-rode the course for my last RR of the season that I'll be racing in next week, and the roads are awful. I'll leave it to the highway engineers to tell me what the material is called, but it's pretty ragged pavement with lots of those wonderful invisible bumps that just jar you as you're trying to ride. No big holes/cracks or anything, just really rough pavement.

I'm riding Conti GP4000's right now, which are nearing the end of their life after a bunch of crits and training rides, and since the Michelin Pro2 Race has a reputation for being a softer tire I was thinking of picking up a pair. But I'm wondering if I should get 23's or 25's.

Any thoughts/opinions? Would 25's help in these conditions?

Michelin say that their latex tubes make a big difference to the roll of the pro2's, could be worth a look, more importantly.. what do you weigh and what pressure you normally running?

200lb, and I usually run my GP's at 110-120.

Sounds about right, I'd stick to the lower end of that perhaps and maybe try latex tubes, they're a pain tho' cause you have to pump them up every day

Hmm... hadn't thought about the latex tube option. It would save some cash, too...

Not really an issue with the re-inflating, though--I check my tire pressure every ride anyway.

My personal opinion is that size, (and therefore inflation pressure) make way more difference than brand, or the material of the tube. So relatively big guy, on a really brutal pavement, might argue for 25c and a little less pressure than you would need to run on 23c. But unless there are big bumps and gaps in the pavement, I think you'd still be ok with 23 c's

And personally I haven't found a big difference with Latex (as opposed to say lambskin) its still a rubber.
