Clutch job wisdom Options

[JeffBowlsby]

So my clutch has just started to slip and it chatters sometimes on launch. I thought I would first adjust it to see if it helps, but may need a new clutch. I have done thsi job before with all the recommended felts washers, flywheel O-rings etc. I don't seem to be having any leakage, burning smells and I have receipts from when I bought the car saying it has a recent new flywheel.

I will do whatever is necessary once I am in there, but don't want to remove the flywheel or do anything not needed.

Assuming nothing is worn or broken (I will replace or resurface things if they are worn), does it make sense that I can get by with just replacing the clutch disk? Can I reuse the pressure plate, T/O bearing, T/O bearing guide clips?

Pelican recommends the 6-spring disk: "We recommend using the 911 clutch package in the 914, as it gives the clutch a better feel." I tried the 6-spring disk once and it was fine of course, but what is the problem with using the stock 4-spring disk (its $125 cheaper)? My car is a daily driver street-use only and with the stiffer disk I wonder if the stronger springs contribute to clutch-tube breakage problems. Help!
