I've had 3 and a half play days (towed too then too) out of a standard clutch in 410..... first clutch done 53k and one play day, 2nd clutch fitted by me earlier this year is now dead! IMHO they just glaze and die...
My 410 is no monster, just has 195/80r15 Colway MT's....
I've got a Paddle Plate From Darren @ KAP to fit now!
