correct you are
you get a mix of albies and bonita. You also run into some of the biggest bluefish you'll find on the east coast. Last year some of the blues we caught tipped the scale over 14 pounds......big ole brutes
If you have the week open, that is your best bet. I would plan to arrive on a sunday, get settled, and start looking to fish on monday or later.
One thing very cool about Montauk in the fall..........TIME doesn't really play much of a factor...... i.e. - there is no reason to be out there at O dark thirty. Sleep in, get a hot breakfast, and work your way outside.
If eeling is your thing, lots of that goes on there as well. I've only ever fishing with fly and light tackle artificials.
