ZF6 clutch recommendations

2002 LB7 with ZF6. I am currently stock but have plans to go up to about 425hp...no more than that.

Currently the clutch is making a tapping sound in the bell housing, I think this is the dual mass flywheel springs having broken. Would you guys recommend a single mass flywheel? I have heard good things about south bend clutch, what do you guys think?
