I had this happen with my clutch, it did manage to come undone so i could go home.
As far as an aftermarket setup, i dont like them, and prefer the stock setup. I do have aftermarket based on the fact that i have a very heavy clutch, and would break it again.
But if i had a king cobra or centerforce, i certainly would replaced the stock stuff.
I also don't drive my car often, so adjusting it manually isn't all that big of a deal.
