I don't post much but read every post

Thought i'd add my 2peneth.
I fitted 4 of the Vred only 4 weeks ago, previous tyre was a Michelin Exalto, which served the car for 23k. The difference in grip level was massive as immediately noticable, no more wheelspin if i set off a little more spirited than normal and I've found myself pushing into those corners a lot quicker than before. So much so the missus doesn't like it anymore

.
Not sure how they compare to your GY's Robin but they are certainly a step up in the grip depertment over the other tyre's i've had fitted (including the Dunlops someone mentioned above).
What i will say is... they do need to be set to a high PSI. I had them fitted by a Vred franchise in Huddersfield they set the pressure to 37 psi. I've read a few posts here and on the other forum about Vred recommending higher. It's certainly true i found at 37 psi the tyre roll affected performance, car was very twitchy under hard braking. I've set them to 41-42psi at the moment and that's improved things but i continue to monitor (as you do).
Overall a fantactic tyre and i can vouch for wet weather grip as well ;-), Terrantial downpour last week and i noticed no real drop in grip.
