36 hole DT Swiss TK 540 rims 73
(think I heard a discouraging word from Andre about the Mavic
rims)
On another forum I'm just now engaged in correspondence with James Stewart of Melbourne, who writes:

Speaking of wearing off at the first application of the brakes, I have
finally damaged one of my two Mavic OpenPro Ceramic rims. I suspect the
real damage occurred a few months ago when I had a minor altercation
with a car driver and his car, that left my front wheel a little
buckled, but I managed to true it up. Upon inspection on Saturday I
noticed a good crack and piece separating from around one of the spoke
holes.
I think this rim made up the rear wheel of a pair I bought some 12+
years ago. It's probably seen more abuse than the original front that
is now a part of my SP dynamo front wheel.
Needless to say, the ceramic braking surface is *still* just dandy. No
appreciable wear to speak of, after a good 100,000+km.
Such a shame no other rim manufacturer has done it and Mavic stopped
doing it. If I could buy another pair of these rims I would in a heart
beat. I don't think Mavic's current Exalith coating is as good, from
what I've read, nor is it available on rims not built into Mavic wheels.

That's contrary evidence from a reliable, high mileage cyclist.
All the same, DT Swiss strike me as a safer choice, even if you never intend leaving the tarmac. Attitude and outlook are important determinants of engineering outcomes, and the Mavic outlook is too closely focused on racing for my liking. Remind me on a dull day, when your bike is built, to tell the story of a supposedly sybaritic Trek for the middle-aged hedonist I once bought, and how Trek's designer, because of the company ethos, bolloxed it from the beginning.
If you can fit wider mudguards, you should. 5mm overhang per side is marginal, even with properly shaped mudguards like the SKS P series. Also, some of those P series have a choice of lengths: make sure you get the longer one, not the short "sports" version. You'll understand why I seem to fixate on a couple of minor details when the first heavy rains fall. At our age you don't want to magnify the miseries of the wet by having water sprayed on your shins, and especially on your expensive drivetrain. Make sure the mudguards have SKS mud flaps, little worthless-appearing things, but they do direct the water downwards. Thorn may just fit them and sink the charge in the general price, or you may have to order them. They're customized to the P series, so getting them later will cost plenty in carriage and nuisance.
[I see in a message that crossed with this one that you've considered this already, but I'll leave it as general comment for others.] Also, is 35mm the widest tyre you can fit, or is it a compromise with some hoped-for "speed"? I am
very impressed with the benefits of fitting the widest tyres your bike will take, since I switched to low pressure balloons a few years ago. You can always slim down too much bike and sell the surplus parts on, but building up not enough bike is more difficult and expensive.
