I would be wary of a clutch with heavier clamping force, the ends on the clutch cable are only plastic and I don't think they can cope with too much more clamping force, certainly I snapped a few with an old helix (pre their redesign)
Oh and when I broke my first CG clutch about 8 years ago they said the springs in the drive plate are only rated to 280lb/ft I assume that hasn't changed.
