Default [Q] Factory Reset & Keep Root?? [Answered]

So I need to wipe one of my Xoom's (selling off the wifi only to a buddy), but I'd like to keep Root/Tiamat/CWM intact.

Can I just do a factory reset via CWM (just want to make sure that's safe on the Xoom), or should I return it to stock and reflash etc...

Thanks for the info

edit: yep...that worked...
