Shimano splines are very
Shimano splines are very small, designed for steel and now manufactured in alloy by aftermarket manufacturers, which just builds in problems. Campag splines are much chunkier as they were designed for alloy from the start. And that’s one solution if you’re running 11 speed, replace both freehub and cassette with a Campag one, they work perfectly with a Shimano or Sram 11 speed setup and you don’t get the notching problem.
It’s not unusual to have to
It’s not unusual to have to adjust the derailleur when you swap wheels. There’s sometimes minor differences. But not usually so much that you can’t get the lower gears… best do a setup from scratch: set upper and lower limit stops, then adjust cable so it shifts properly. Shimano’s an Campag’s tech docs explain how to do it, its reasonably straightforward.
I only drink water on rides
I only drink water on rides these days. I’ve tried all the isotonic drinks and so on, sometimes had one bottle of carb drink and one water, but now just water and food: bananas, High5 bars, and so on. Never liked the taste of energy drinks.

OK, these are definitely post
OK, these are definitely post-2015 as that round thing is a date stamp that says ’11/17″ when I looked closely – and the graphics on the levers are different from my 2011-2014 pair.
So this means I have a pair of slightly scruffy post 2015 Chorus 11 speed shifters for sale, perfect mechanical order, if anyone is interested.Update: sold.
Yes, perfectly compatible

Sorry, I mean there are
Sorry, I mean there are usually several ‘permitted’ combinations, and they’re usually marked, so both the 53 and the 39 will have ’53/39′ marked on them, as will the 52 and 36 of a ’52/36′ combo… that said, things like this normally work fine, if not quite as effortlessly as the ‘matched’ combinations do.
Chainrings come in matched
Chainrings come in matched pairs, so if you have a 52/36 crank, and add a 39, unless you get the right 52 tooth – made to work with a 52/39, not a 52/36 – then shifting might be less than utterly perfect. But I would have still expected it to work, even if it’s a bit rough!
The other possibility is that you’ve managed to change the stop on the front mech so it doesn’t move inward far enough.
Could you upload a video of the problem?

+1 for handbuilt. You’ll get a much better set of wheels for the same money.
I have a freehub on some
I have a freehub on some American Classic hubs that needs a 0.7mm spacer behind it or it binds, but that said, no probs with my Prime wheelset in that regard.
I think this is all too
I think this is all too pessimistic. The statistics are very clear: cycling is less hazardous per hour than walking (marginally), and we’d all walk without a second thought. More importantly, the dangers of NOT cycling – inactivity, obesity, heart disease, cancer, dementia – are much higher than the ‘danger’ of cycling. David Rojas-Rueda’s study* estimated benefits as 77 times higher than the risks; others have since found similar results. We have an syndemic of inactivity in Britain!
I cycle on roads and have done since the 1960s. I see a few close passes, but what really strikes me is how careful and courteous most drivers are, holding back until a suitable place to overtake, often quietly without me even noticing they’re behind. In return I let drivers turn in front, sometimes pull over and let them past if there’s a safe place to do so, and always give them a wave when they pass wide. Yes there are idiots, but they’re a minority.
My hunch is the relentless pressure of YouTube ‘close pass’ videos with their aggro and hype is building up a false picture of the reality of cycling on the road. Having a camera I expect makes some of the authors feel the need to post footage just to keep their viewing numbers up, when many of the passes are normal and unremarkable. I’m probably doomed now I’ve said this, but really, in the UK the benefits outweigh the risks by a huge factor, and we have so many quiet lanes all over the country, it’s not hard to find a nice route leading to where you want to go, and the gradual increase of segregated lanes and quiet back routes in cities helps keep cycling hugely pleasurable.

You could get some much
You could get some much better, lighter wheels built for that sort of money. Talk to David at DCR wheels, he built some lovely wheels for me that are lighter than either of those, and can be rebuilt when the rims wear out. https://dcrwheels.co.uk/
Other wheelbuilders are also available, I’m sure others will have recommendations.

Yes that’s right, Southwark
Yes that’s right, Southwark Cyclists say they can’t get insurance for the coaches should they have to cancel, so they can’t risk it:

The good news is that an 11
The good news is that an 11 speed Campag cassette will fit perfectly on a 10 speed Campag spline (Campag freehubs are 9, 10, 11 and 12 speed compatible) and an 11 speed Campag cassette is perfectly compatible with 11 speed Shimano shifters and derailleurs (and vice versa). It’s one of those rare occasions when everything works nicely together, and there’s no need to change anything in your hub.
