is this a silly idea? (surf fishing in Florida)

Hi,

I am a complete beginner in fishing and my only experience so far was
fishing in the Mosqito Lagoon in East Central Florida, close to Cape
Canaveral. Using a 6 foot rod, a braided line (20lbs equivalent), a
metal leader (also 20lbs) with a swivel and a snap (I know, this is a
newbie's sin, but it allows me to changes lures easily) and a Jonhson's
Silver Minnow (which is actually golden) I caught speckled sea trouts.

I am thinking of trying to catch some fish in the surf off the closest
beach. All the fishermen here use very large fighing poles and live
bait so I wonder, is my idea of using a small 6 foot rod with my
braided line and my Johnson spoon really silly, or might I still catch
something?

(I do not have the money for another rod, nor do I feel comfortable
changing my line, but I would gladly use another lure if advised to do
so).

Any advice/comments would be very much appreciated!

Kind regards,

TN
