Yeah I've backed up my stock froyo with bootstrapper and titanium.. so if I download the liberty 2.0 rom and then want to go back to stock froyo it wont be difficult will it?

Its VERY easy.
Once you backed up in bootstrapper, and installed Liberty or whatever you want, I would make a backup of your new ROM too.
If you ever want to switch back to another saved backup, do this.
1. Open DX Bootstrapper
2. Click the first option
3. Click the second option
4. Use volume rockers to go to Backup/Restore
5. Click restore and choose the file named after the date you backed up
6. Your good, and it may take 5-10 minutes, possibly more.
I have done it about 10+ times.
Again, i'd recommend Liberty for your first ROM.
They have a Liberty Toolbox app that gives you several easy ways to customize, making it simple. There are 15+ themes to choose from to, by going to download ROM option in Liberty TB.
Its also very fast and stable. Then again, basically every ROM is better than stock Froyo/GB, so its up to you.
