Poll: Lightweight flywheel or stock?

Ok guys, I need a new flywheel on my car. Here is a build thread so you can see what it is: http://www.d-series.org/forums/entertainment-area/165724-10-1-1-z6-forged-internals-build.html For those of you lazy guys, its a 10:1 z6, staying NA for a few months until after tax season, then a dsm small 16g converted to a 19c will be going on it.

My question is, I'm broke and I absolutely need a new flywheel. My Exedy one has been machined too much and it is now too thin to use. A new one is $220, but I have a stock one with a ton of meat on it just laying around that I could spend $30 on to get machined... I remember when I went from the stock one to the light one that it made a pretty noticeable difference in acceleration so I would really like to put a llightweight back on there. I'm just strapped for cash right now with christmas around the corner and I'm not sure if it's worth it. Let me know what you think.

Especially you guys running stock flywheels, I already know how great lightweight ones are, but I'm most interested in the opinions of people who have had both.

UPDATE: I did a comparison write-up on page 4.
