Nice one, lovely bike.
Have you been out with mates on 26" wheels at all? In the direct comparison the benefits were very obvious to me.
FWIW I'm down to 18 Psi Front - 20 rear Psi and often a bit lower than that as tires lose a bit of air .... YMMV Note there are not many rocks in Holland and I started with 25-26 psi a while ago tgoo. But I just kept going lower and lower, getting used to the feel and adjusting my style. I even got me a low pressure pump to have some resolution in the dial between 15 and 20 Psi.
The increases in comfort and traction resulting from dropping the last few Psi are significant.
Yeah personal taste, run mine about 25 and that works for my lardy arse and as the man says you really feel the difference esp if you are rigid up front.
