Hello List,
Are there any strong opinions one way or the other regarding the Moss clutch 
choices for a TR4 (&4A)? 

There are quite a few clutch choices; 
 standard  TR4 Kit is  $234
 standard TR4-A Kit is  $140. 
'heavy-duty' TR4-A Kit is $300. 

The pressure plate I have now has very low miles (standard TR4 coil spring 
type) and my plan was to clean up the surfaces of flywheel and pressure plate 
and put in new friction disc for $80.
Now wondering if the 'snappier action' (half the foot travel to disengage) of 
the TR4-A clutch is worth the expense to change up. (pressure plate, friction 
disc, throw-out bearing and bearing sleeve)

And if the TR4-A clutch was better why did they have to develop a 'heavy 
duty' version (offered at double the cost)?

Is the standard TR4 clutch more rugged/reliable than the standard TR4-A 
clutch?

Horsepower when I am done will be slightly up - maybe 110 if all goes well. 
And I'm installing the overdrive unit (adding more weight to the spinning 
drive train). 
Not thinking of racing the car - well .. maybe years down the road  :-)

Any thoughts on choice of clutch for a slightly upgraded 'sports-driver' ?
