Changing from 11-28 to either 11-32 or 11-34 cassette...

Everyone has said all the stuff I would have said (SS vs GS, capacity, chain length blah blah)

But good luck with it. Go for the 34!!

Not much of a jump really. Why not 11-40T with a long cage derailleur?
10 speed being mtb compatible you can buy both very cheap.

My switch to a single chainwheel 11 speed setup was 11-50T.

You sure about that ?

"On the other hand, the 4700 series is quite special. Not only is it incompatible with the TIAGRA 4600 series, which is also 10-speed, but it is also incompatible with the old ULTEGRA 6700 series and the old 105 5700 series, making it a component that can only be used with the 4700 series."

'Special'.
Hmmm.

'There is almost no interchangeability between the 4700 series and the 4600 series, but for sprockets, there is no such thing as a 4700 series sprocket, and the CS-4600, CS-5700, and CS-6700 can be used with both the TIAGRA 4600 series and TIAGRA 4700 series.'

A good clean up - 5 watts saved. Must be equivalent to an extra 2 teeth on the cassette for starters.

Something I learned many years ago was: if you're going to post pics of your drive train on CC, clean it to within an inch of its life first.

Definately.

I won't get out my old DA 7400 cassette picture then ! Bling.

Should I change the rear gear cable while I'm at it?

It's not been changed after at least 6 years of daily use.

I would. Not for any scientific reason. Just because- as you say - you may as well while you're at it. It will only make the job marginally more tiresome, and it gets the task out of the way.

For sure, I'd probably change the housing at the same time.

Excuse my ignorance. What do you mean by housing? Is that the cable outer?

Yes, the inner cable will inevitable pull some dirt, debris and water into the housing as it's used - replacing both the inner and outer part periodically will make shifting much smoother and give it a lighter action.
