How much do you puncture? Is it your everyday bike?
I’ve not gone tubeless road as I just don’t puncture very much and can’t be bothered with the faff (plus I like swapping wheels/tyres between bikes etc.).
Also, I think the road.cc review referred to a test by one of the German magazines that showed that a clincher GP5000 with a latex tube was lighter and rolled faster than equivalent tubeless GP5000. Not sure what results were with a standard tube.
I run GP4000s with latex on the summer bike, all I can say is it rolls noticeably faster than the winter bike with 4seasons and butyl tubes, and I haven’t punctured yet.
Edit: unless you’re worried about aero watts I wouldn’t be concerned about tyre widths on a 17mm rim, I was running 2.3″ MTB tyres at 30psi on 17mm rims not so many years ago…
