Pressure plate question - cast iron vs aluminum

My clutch was giving me issues, needed to replace it. I had a Sachs "Power Kit" and looked at my options: Anothr SPK, Centerforce, or Kennedy (or stock, I guess...)

The consensus (from what I read on various threads) seemed to be that the Centerforce was way overpriced for what you get, which was a modified Sachs PP and a stock disk.

So I went out on a limb and ordered a Kennedy "Stage 1" clutch kit for my 911. It arrived today, and it turns out it is a Sachs cast iron pressure plate. Is it just me; I don't see how any sort of 'performance' clutch can be cast iron. This cast iron PP weighs a bunch more than the aluminum one, and for a 95% track car I don't want to give up any performance I don't have to. Between the chip and AFM tuning, I didn't have too much of an idling issue with the aluminum PP.

I'm tempted to put in the new disk with the old aluminum PP and call it a day.

Thoughts?
