I currently have a generic stem and i think, a riser bar. Both were stock on my GT. What's the advantage of going to the Easton (or other brand stuff), besides it looking a little cooler?

Riser Bar vs. Flat bar? Weight savings? How do I determine if I need 0 degree or 10 degree rise?

I will mostly be riding XC, not much downhill. Thanks in advance!

What you need to ask yourself is this: "What is really wrong with the bar/stem I have now?". If your bar/stem combo is in danger of failure or does not provide you with a comfortable and technically sound riding position, maybe it does need to be replaced.
Don't waste your money upgrading something that doesn't need to be upgraded. Around here, the terms "looking cooler" and even "lightweight" don't mean very much. I'm most concerned with "doesn't break and land me on my face", followed by "lasts a long time", and "cheap". Then again, I ride a mid-level hardtail, with mid-level components which is not very cool.
