I went for Falkens in the end. Just taken them off after around 8000 miles use and put my winters on - happily the wear on the 19" Falken tread is
a) minimal, but more importantly
b) even across the tread
Early days, but it seems these wear better than 19" RFTs on the rear.
Pic attached (middle 2 tyres are the rears - rubbish photo as I must have moved the iphone as it was being taken.....
