Thank you all for your comments. I have indeed been considering Eldar (either corsair or craftworld), but the expense of their ships makes me want second opinions before making any purchases. Of the above eldar variants, I would love to know which you think fits my needs better, but then I suppose I need to tell you a little more about what I am driving at.
But first, you asked for my SM fleet list. I have played around with a number of small (750-1000) lists, but they largely come in two camps:
Battle Barge backed up by Hunters; and
Battle Barge backed up by Strike Cruisers.
My usual opponents are ordinance heavy Chaos and Imperial, but I have been driving a BFG revival at my club and we have about 5 new members, so my opponents will begin to vary more.
With the escort fleet I typically drive my Barge towards the enemy fleet AAF so I can bring the guns to bear and to draw fire away from the Hunters. Hunters hit one flank or the other. After the first pass I tend to disengage, as I don't do well in slugging matches, but I have often crippled or destroyed enough enemy ships to pull a minor win. I typically get one LO with the Barge before being perma-braced, but I have never had the barge crippled, let alone destroyed.
The Cruiser fleet is a bit more fun, and typically involves the defensive use of ordinance to aggressively board enemy ships with multiple SC. Again, the Barge is a fire magnet, but it sometimes gets to board/ram, which is always fun. Again, that damage stacks up pretty fast on my SC and I often find myself disengaging while I am ahead in points so that I can pull a win. This leads to my feeling defeated even when I technically win. After all, I ran away, didn't I?
Edit: Rereading this, one of the things that jumps out at me is how much I dislike the "damage sponge" role of my flagship. With little effective range and the lack of maneuverability that comes with it's size, I always have to move aggressively with my largest investment or risk being pinged to death by long ranged lances (chaos) or nova cannon (imperial) with no effective response. I feel that the "it-ship" should have an exciting role to play. It should be zooming around the battlefield spreading death. Instead, my opponents just do enough to keep it braced and then avoid it (and being ordinance based, this is not difficult for them to do).
