I finally went up Sheridan into Wisconsin last year for the first time in many years. Worst ride of the season. Constant close calls. I thought for sure I was eventually going to be hit or shot.

I didn't, really - for whatever reason, the new set of Ultegra levers/calipers came with metal pads installed, so I figured I'd give em a chance and use em.
Side note: I hope these things get considerably better after they bed in, because their stopping power is ass compared to resin so far.

This is all mostly with SRAM. With Shimano just about everything works great right out of the box.

Yes, the rim is the largest rotor you can have, but it has to work as a braking surface while fulfilling its other functions. I think the biggest potential benefit of disc brakes is the freedom to design rims without the constraints of having to accommodate brake tracks. You could optimize rims and brakes for their respective roles, without compromise.

Not exactly. Higher leverage means that you can get more clamping force for a given hand grip force, but it also means there's less pad engagement for a given lever travel. High-leverage v-brake setups can have a higher risk of bottoming out the lever against the bars before maximal braking is achieved, unless everything about the setup is very stiff and everything is very true and set close.
Cantilevers can be more prone to housing compression since the shorter pulls produce more cable tension, but if that's stiff, a good canti setup can produce quite a lot of clamping and fork flex. Case in point, check out these pads on the Tektro CR720s on my Campeur:
I foolishly set them up flat to the rim, and they went ahead and toed themselves in fairly dramatically. And that's not just in the brake mechanism: the flex under strong braking forces is clearly visible in the front rack, which has its upper mounts on the canti posts.
Interestingly, I see much less of that effect on the Deore T610 v-brakes on my gravel bike, which also gets a lot of hard stops on paved use. Those brakes also feel quite stiff without any boosting despite having very high mechanical advantage, but they're on a very beefy frameset, originally an early-80s MTB.

CR720s are OK. I stopped messing around with mid range cantis a long time ago though. Pretty much it is Avid Shorty Ultimates or it's not worth it. Couple these with Yokozuna Reaction brake housings and you can rip a fork or a brake bridge off any frame and actually stop well.

People aren't riding 28s and 32s with rim brakes, but those are pretty common with discs, and the bigger tires make a bigger contact patch. Disc wins again!

*sideeye* we ride 28's and 32's with rim brakes all the time... Remember canti's are rim brakes. Around here the cross scene is so bike we have all had our "gravel" bikes for over a decade now and many are still knocking around cantis...

The 15 miles between Northwestern and Ft. Sheridan is one of my favorite stretches of road in Chicago. I'll see a couple-hundred riders on a nice Saturday morning in the summer. North of Great Lakes sucks.

Yeah and right at Great lakes is when I cut in- heading north. I was in Lake Bluff for the race that day and decided to take a ride for myself. Used the North Shore Century route as I had ridden that a decade before and remembered it being fine.

I just flushed my Shimano discs . I just bought this bike...a 2016 6.9 Domane and it is a little under maintained so I figured flushing is good. It turns out flushing was really needed.
Picture ! is now but picture 2 is what was in there...it was about time I would say.

Sorry, I'm not familiar with your product line. I hope your cross wheels have been well received.

Not because they were enlightened, but because weight weenie marketing told them 1/2 oz is significant, when its really not.

There are a lot of elegant and sleek road brakes out there, those aren't one of them, the term chunky comes to mind. I've got some old modolos that would fit the definition better IMHO.
It's easy to run those on a number of road calipers, the first season I decided to try cross I some green vittoria 32s on my road bike of the time and ran with ultegra calipers. Did fine the first 3 races till the wet season really hit though the mud clogged the frame just as quickly as the calipers. If the frame went slightly out of true the rim and tire still had no problem clearing the brakes but the frame was the limiting factor. Disc is really allowing for the wider rims to run bigger tires to greater advantage without having to mess with the brake geometry of Vs or Cantis which could have pad clearance/leverage issues with a wider rim.
Alloy is all about the color, weight is just the bonus. I can remember people worrying about the weight and being one of those people. Now I build all my/my families' wheels with nipples from wheel fanatyk since I really like adding the colors while the spline are a lot easier to get to tension with no effort. Something I liked when I learned to build in the late 90s and spline was first available.
