Clutch Recommendation: Part II

[69sixpackbee]

I've decided on the diaphragm-type clutch (thanx for the help ) and am now narrowing it down to one of two types...Regular or "Heavy Duty"...
Does anybody have the so called "Heavy Duty" type diaphragm pressure plate (specificies that it has increased clamping force and increased pedal effort) ?

I am removing the Borg & Beck type..my knee will thank me...in favor of the diaphragm one.

Will the "Regular" duty diaphragm one bee sufficient for my camper-hauling-around vacation truck or should I opt for the "Heavy Duty" version pressure plate?

I figure that even the heavy duty one should be less pedal effort than I have now because of the "over the center" locking ability of the Belville spring construction.

Is the heavy duty cover a watse of money over the standard duty version?

Thanx again,
Bud
