The utility cyclist wrote:GP4000 "delicate", I don't think so, measured thickness at the tread is similar, the sidewalls are 0.15mm thicker on the 4S (according to BRR). The OP wants a supple tyre, the 4S really is not a supple tyre, it's okay for what it is but there are a lot better and cheaper options out there that roll better and give decent puncture resistance.
Of course if puncture resistance (at sides and through the tread) is your main priority then you do tend to suffer in the supple/fast rolling stakes, for me as a 100kg rider I didn't like the 4S, I found it to be lifeless and not particularly fast rolling, I found a tyre that I liked that was far closer to size, gave me feedback and rolled better. Everyone has their opinion, that is mine.
28mm GP4000S are 260gr, 330tpi, Black Chili compound and Vectran layer
28mm GP4Season are 280gr, 330tpi, Max Silica compound and double Vectran layer +Duraskin
Having used extensively both tyres, on different bikes and situations*, you definitely get more punctures and cuts (especially on the sidewalls) on the GP4000s than the 4Season, altogether with the numbers above the GP4000s is certainly more delicate.
If the GP4 Season does not feel "supple" I'd check the bike and wheels, something's not right
* I think I've used a few Continental tyres over the years, to have a good idea how do they ride:
the Condor light tourer has used GP GT 24mm, GP4 Season 23 and 28mm, now GP 4 Season 25mm
the Condor Track I had was using 23mm GP4000s
the Cinelli s/speed has almost always used GP4000s 23mm
the Cinelli SC has used GP4000s 23mm, Challenge Strada, Vittoria Corsa SC (only because have gumwalls)
both the Pegoretti's have used GP4000s 23 and 25mm, the steel one has now GP 4Season 23mm
the alluminium Cinelli road has always been using GP4000s in 23 and 25mm, and GP 4 Season 23mm too
and the Union s/speed is using GP GT 25mm
and I'll pass over the Mtb's
