For me, F4 is "good race". Have people changed from trolley drifting to trolley racing? I think the tyres on trolleys have got a lot less durable, to be honest.
I use hybrids on the rear, especially in Tescos. Them damn slippy floors make bits of supers...Although I do prefer going cruising at Supervalu recently. Drifting heats up the clutch too much for me
