I'm a broken record on this one.. but I cant stress how good the UAD compressors are. And the nigel does wicked things to anything you run through it.. Maybe too wicked.

beyond card based VST.... my top regular efxs are...everything mentioned above + Antaras Filter (great filter and built in delays). Also I'll open reason and run something through it just so I can let the Scream give it some lovin.
