Ubuntu :: 10.10 Maverick - Default Swap Size?

I recently upgraded my laptop from 10.04, to 10.10. -- And in so doing reinstalled the OS from scratch, and letting the system pick the partition sizes.

Code:
My system:
2GB RAM
160 GB HDD
HP 6910p

Here's the question: The Installer set aside 6GB as Swap space, leaving 154GB as a / partition for everything. I had always thought 2GB was plenty, or as a general rule twice the Physical Memory size, which would only be 4GB swap, not 6.

Can / should I reclaim some of that swap space, if so how much. -- I can using tools like GParted to resize the partitions. -- Or just leave it as is. Unfortunately, the Ubuntu 10.10 installed did not seem to use GParted, so it was a little harder to set up initially.
