Picked a wet morning to have them put on but have to say that I felt better riding home on PR3's than I did going to the tyre fitters on Scorpions. I rode home via a large new industrial estate which has good roads and lots of nice roundabouts - even though I was being cautious due to combination of wet/damp plus new tyres - it felt good.
Hope to get some dry miles in over the next week to fully scrub them in.
