Depends on what you want,and how you treat a clutch.
If you want to retain the stock feel,then the Sachs organic and LUK DMF will cope with up to and maybe a bit over,400lbs.
It will not,however,cope with a lot of drag style starts.
The Loba/SMF is tougher,but there is the harshness aspect,which isn't bad,but will be noticeable at idle.
