anyone able to comment on the drop-off on the GRP's?

The drop off in performance was pretty minimal as you can guess from Tom's previous comments..
I ran the same set through qualifying and did my fastest run and lap times in round 4.... The car still felt really good on the tyres with no real loss in grip levels...
Bradders then ran my car for 7 mins in the time between Q and F so I bolted up a new set for the final...

As with any tyre there was an initial 'edge' to the tyre in the first few lap until the tyre settled down... there was almost no difference in lap times.

People did seem to think the tyre wore visually more, but the spike is designed to carry on working once the initial edge is gone.. this was the main thing that we looked at.. The spike profile... To keep the best grip level for longer, this will mean the average club racer will get more life out of his tyres....
