I would not suggest using a 10ft Exage for estuary fishing... it's complete overkill and there are many other CHEAP options which would give you MUCH more joy in estuaries - thinking rods to cast weightless prawns, small dropshot-lures and small plugs/spoons.
...and I'd pair it with a small grinder, 2000-4000 size. 10lb braid is plenty, 15lb if you're very new to estuary fishing. Just my 2c, but I certainly won't fish an estuary with a multiplier reel...
