I run a hybrid list with Plasma-Vet forward Element, and Gunline quarterbacking and transport popping.
Truthfully, as good as it looks on paper, relying on precision shots from single-character squads is pretty shaky. Putting them on a mobile blob is one thing, because you have four chances to roll a 6 in a 31 man blob.
My
CCS sits with a Lascannon next to my lascannon gunline blob passing out
BiD. I have found a lot of success with this, because you can reliably keep transports away with that volume of S9AP2 twin linking, and once the squishy contents of the metal boxes come into range,
FrfSrf does quite nicely. Keeping your
CCS back there also keeps the Warlord Killing
VP relatively out of your opponent's reach.
PCS' are really more of a filler squad, five customizable dudes you can kit out for whatever you need. Need some sexy Anti-infantry killyness? 4Flamers does wild things, even with the low
AP. Short on plasma, or got enough points for another chimera? 4xPlasmagun in a box. 4xmelta is still viable as well. Me though, I run them with either an Autocannon or a Lascannon and just merge them with the Wall of
AT behind my aegis.
As I said above, I don't find much use to waste points on an officer to make him capable of handling challenges. What with every other codice's excellent
IC's and Characters, the chances of an Officer actually doing much seem so negligible that I'd rather just take another plasmagun somewhere, or even some camo netting. Then again, I keep my warlord behind a blob behind an aegis behind a wall of Chimeras, so he doesn't see much action anyways

Which, if you think about it, is how a good general would operate.
