Corbina (aka Corbs, beanies, grey ghosts) are similar to Redfish in general body shape but a little longer per width & height. They also don't get very big. A 5#er is a trophy to most people. They are generally very spooky (think bonefish)and love the shallow surf, feeding on sand-crabs. They are generally fished for with light weight freshwater Bass type rods.
The gear you have sounds like it might be better suited to White Sea Bass (WSB). They aren't actually a Bass but a Croaker, similar to the Corbina but with a upper size limit that is BIG. The World Record for them is something in the range of 80#. Most surf caught fish are around 10# though. They love Squid and will eat white iron (Drone jigs in East coast speak?). In my experience they rarely are in actual surf areas.

Tight lines,
