I have just the standard rear stand that you lift from the back, and I recently bought a roll-on front wheel chock (
http://www.cyclegear.com/TRACKSIDE-Roll-On-Wheel-Chock - $79 on sale). I really like the front chock for general maintenance as it hold it much steadier than my rear stand.
When it's in the chock it's super easy to lift the rear wheel with the rear stand, so there's no more balancing-act going on.
