Thank you so much for so generous a response. Looks like I’ll stick to 11-29 then and try and find a second hand compact chainset then!
ghostface-
You’re in the nice position of having an abundance of 11sp rings at your disposal. If you feel really overheated, you may find sub compact (I.e 48/32) works for you. Not sure where you live but I live in a valley between sizable hills and actual mountains - there’s only one descent I spin out on in the area. Lots of people think they’ll be under geared with sub compact but I don’t think most will be. And you’d have the benefit of almost 1-1 gearing.

You can check either the rear mech / chainset i.e. it should show a small white sticker with a code. On the rear mech this should start with RDxx-SRxxxx. The two digits that come after RD indicate the modelyear.
The same goes for the chainset. This code should start with FCxx-SRxxx. Or "CH" in case of Chorus.
The 29T is indicated for a reason. If you run a less than ideal chainline / length, shift under load etc etc it's likely for the rear mech to snap and come off due to your simply exceeding its outerlimits.
Reason I'm curious to understand the modelyear, is that it might be safer considering changing to a 52-36 up front i.e. instead of exceeding the outer limits of the mech. From the moment Campag moved to the 4 arm crank design, the BCD became similar for all chainring combinations.
Meaning you can easily swap between fixed combinations of chainrings.
Anything based on the 5-arm design had a dedicated BCD for 53-39 / 52-39 and a different one for the 50-34 and 52-36.
If your groupset is from 2015 onwards, you could look for the medium cage rear mech although in this day and age they might be hard to come by.
It used to be available in Chorus / Record and Super Record when they were still in range components. The Chorus RD (medium cage) is now available to order as a spare part under RD15-11CH2SP. This will only work with 11s drivetrains from 2015 onwards.
