Please link to these tyres at £25. Rolled some a few years ago (in 25) and was impressed. And think they do 28s now.
Sorry, that was a guesstimate - best I can see on a quick look is Decathlon at £30

Having accidentally discovered one summer, through failing to check tyre pressures regularly, how comfy Gatorskins became at reduced pressures I experimented with reducing the pressures in the 700 x 25 GP4000s I had on my summer road bike at the time.System weight and tyre width for me is the same (but with Conti GP4000S2 28-622 - I have a few left).
50psi on the front is rather low and you risk snake bites, imho: the tubes are not made of 'gatorskin'.
YMMV
The graph below is from the BQ article by the famous Jan Heine (2006) (attached).
Having had a significant off (ICU etc) fast downhill bitd I add 5psi to the values shown. This also means if I haven't recently (ie this week) checked pressures I can be confident that there'll still be sufficient pressure in the front tyre to be safe.

Yes mate, but not delivered yet.Do we have a purchase yet? The suspense is killing me.

I went for Schwalbe Durano DD Addix RaceGuard Wired 700c Road Tyre 700 x 25c.
£23 a pop, pardon the pun.
I found the Pro 4 a little slippy when new in 25 guise. They did start to puncture and wear quite badly after maybe 2500 miles (in fact the punctured rear was slightly spilling its hairy innards prior to replacement with Rubinos!)
It is never easy to mount Marathon Pluses. But I have done it with levers. And now that I have arthritis in my hands I expect it might be even harder. But people do it all the time and for me, the extra puncture resistance is worth the risk of having to remount the tyre. Actually getting tyre pressures right was almost as much a pain. Over the past year I have ridden my Airnimal Joey at 60psi (my first choice) then 45psi and then 40psi. Yesterday when I collected the bike from the bike shop where it had been for a service, I found the shop had pumped both the tyres to 50psi and they were perfect. I learned two lessons. One is that 50psi is indeed the correct right pressure for me and the Joey's 24in x 1.75 in wheels. And two, always listen carefully to the bike shop folk. They will have had a great deal more experience on a wider variety of bikes than I will ever get.
