Clutch for AU3 220

[Sox]

Howdy gents,

What clutch kits have you used in your 220's?
Mine hasn't failed yet, however we're about to do a 3500k trip towing a caravan in October.

The current clutch is as far as I'm aware the original unit, and the car has done a frag over 120,000k's.
It is weak as it as one good hard launch has it slipping and smelling somewhat.
Just reversing the caravan into it's carport has it smoking as it's slightly uphill.

So, I'd like something which doesn't have much more pedal pressure, as it's a pleasure to drive with such a light clutch, however I know it may need to be a little heavier due to extra clamping force.

I also don't want to spend a bomb on fancy branded units, when well designed conventional units will likely do the job just fine.

Proper experience would be good, not just a 3 second burnout in your mates sisters uncles neighbors yada yada yada.
