Clutch Masters Stage 1 vs. Stage 2

My '03 6 needs a new clutch after 66,000 miles. I've read up on here and it seems that the consensus is to replace with a Clutch Masters Stage 2 and the Fidanza lightweight flywheel.

I see that the stage 1 clutch is about $120 cheaper than the stage 2. Since this is a costly repair, I wouldn't mind saving that money and getting the stage 1. My question - is it a huge difference from stage 1 to stage 2? Is it worth the extra money?

Thanks.
