Was running a set of Nobby NICs and they're pretty good fast, light, grippy too, this is someone coming from high rollers/minions/barons. The NICs, particularly the front was a bit flimsy when used hard on dh tracks so would swap three for such days.
Thought I'd try a Hans dampf on the front to negate tyre swaps, but its a bit rubbish really. No grippier than the nic but heavier and far more clumbsy.
They seem a bit pointless. I played with pressures too. Are they just a bit rubbish?
