I think the real problem is you need a new job..
I had a an exedy HD safari tuff clutch in my ute, driving 8-10 hours a day, 5 days a week your leg gets stronger after a while and you dont notice it..
So i get a new BT-50 and all i can say standard clutches are f**kin rubbish It feels all wrong ,doesnt bite when i want/expect it too and even though its only done 50oook i want to change the clutch it shits me that much with its lame spongyness.
But guess ill have to wait till it dies which could be a while, I know guy with 330,000kms on his stock clutch
Harden up princess..
