Is funny how people get on with some tyres and not others. if you’ve been riding 4 seasons and are use to the way they feel I’d say go with GP4000S. Will feel better but likely still familiar.
I find GP4000’s fragile even for the nice bike.
Similarly some people find some tyres fragile, others don’t. Maybe it’s a local roads thing, the type of grit and stone you get on the roads might suit some tyres better than others. Maybe you’re a bit heavier or lighter. Or maybe you run a specific pressure. Or maybe the particular tyre just happens to work well with the tube you use. Or it might just be luck.
Like I said, I’ve had good year round experience with GP4000S. Though I run with vittoria latex tubes and set pressures before each ride.
Got some Pro One’s to try next as I recently got some tubeless compatible wheels. Not entirely convinced but shall give it a go.
