9/10 for soloing. I would be a little curious as to where party or raid frames go as well as how your buffs look when there are substantially more because if that bar is set to just grow upward it will end up taking up a lot of screen space.
Here is my current UI taken from a heroic pick up group. Hard to really tell but those Eclipse icons in the center of the screen are actually a vertical SexyCooldown bar modified for proper handling of the 3.3 Eclipse cooldown changes. In raid Grid would take the place of the party frames.
