Ralphs are certainly a good tyre, I personally prefer the Rons, lighter and grippier, happy to sacrifice durability personally.
A Ralph has more tread on the shoulders than a Fast Trak, so it’ll corner better, doesn’t really have much more in the middle, but they are lighter, so you should find them faster.
Tyres are so personal, but IMO a hill like that in the Gorrick was so loose that a nice light tyre is probably better than a really chunky one, a smooth pedal stroke will help. FWIW I cleared it 3/4 times with Rocket Rons and a 36t single ring and some wheel spinning. I was going to use Furious Freds, and whilst they’d have struggled elsewhere, I’m not sure they’d have made all that much difference on that particular climb.
