I plan on hitting up Bronte soon. There is also the Fisherman's pier (Hamilton), which is just as close. A few salmon have been caught there too.
As for rigs, I use a 6'6 M St. Croix Premier, paired with a Shimano Sahara 2500FD and 10 lb Fireline braid. It really is a nice cheap combo.
Tie on a high quality snap swivel on the end of your line (make sure to use realllly good knots), and then clip on a heavy spoon such as a Cleo to your swivel. My favorite Cleo is the 3/4 oz silver/blue model. It catches all kinds of salmon and trout, but you can experiment youself and find your own personal favorite.
For techniques, basically lob them out as far as you can, count them down to different depths, and retrieve. Nothing glamorous really, but it does catch fish. You can experiment with different lure colors, depths, and retrieve speeds.
Get out there and tell us how you do!
