roseville looked pretty brown yesterday. i don't think that is too conducive to good squidding... i think they're a visual hunter - just have a look at those massive eyes.
palm beach used to be good but the wharf tends to get a pounding by the squidders (myself included in the past).
slow retrieves, close to bottom, quality japanese jigs and various colours are essential. i prefer the duel and daiwa jigs. bigger jigs for bigger squid. don't be afraid to go 3.0 or bigger, even small squid will hit them.
good luck.
