Head west dude... wherever there are sand & waves, there will be perch, also any of the jetties will produce perch, just focus on the surf side of course! As for tackle, yes, perch do tend to have small mouths, but I did catch one that still got a size 1 into it's mouth. The size of hook in my opinion should be dictated by the bait you're using and whether you're going after the big boys or not. But in general, yes size 2-6 should work just fine. If you're concerned about gut hooking smaller perch then I recommend tying loop knots on your leaders so that it greatly reduces the chance of hook swallowing and the bonus is that it provides a more natural presentation as a result of the bait having relatively unrestricted movement. In terms of weight, surf conditions will always dictate what you'll need. Note: You don't always have to have your weight sitting on the bottom to be in the zone, sometimes a very slow retrieve can coax some bites. Line is a personal preference, but should also be dictated by the surf conditions in addition to how much weight you're using.
