I used to use 7 Rattlesnakes + Gardes, two Basis, and a Huginn / Loki for VGs, and it went decently.
If you use the Huginn, you need a LSE and you need to keep transversal against any Deltoles that spawn as they can insta-blap you.
Loki can just rig + dc2 tank with a 3web 2painter setup.

http://puu.sh/c1fRi.png My old setup, before I re-arranged a few things.

The basis were 4/2 setup FYI. I had all my videoFX on my primary toon (the webber), and I was able to quickly switch logi targets without leaving my primary toon's screen.
Rattlers were 2 invuln + EM fit with everything else dedicated to drone damage or range.
Loki was 3web 2painter, 1 dc2, and the rest of the lows were occupied by Signal Amplifiers. Highslots were a handful of civilian guns and a tractor beam.

I imagine the Ishtars might do well, but IMO I'd try out a set of Gilas w/ Hammerheads on the test server before Ishtars. LordsServant can attest to the Gila's firepower.
