Scorpion trails here as well. They performed really well for me in Scotland, all dry riding. A mate I was riding with kept commenting that the little Scorpions on the edge of the tire were worn away

I did have some twitches from the rear end with the Scorpions in the wet.
After a puncture I have just fitted PR3's so far seem good, but not had a chance to work them hard yet.
The fitter I use had fitted Metzeler Z8, to a couriers bike, the guy who used it wouldn't have another one fitted when it wore out. Couldn't get any info as to why or what bike it was.
