What type of stick for casting plugs off surf?
9 or 10 foot. 8 or 11 foot if your so inclined.
Line weight should be rated for 12 to 20 or 15 to 30 pound test -
1 to 5 ounces. 2 to 4 ounces or 3/4 to 4.
In that general area.
There are many to choose from.
Assuming you dont want to spend anything.
The Penn Power surf stick is not horrible for the money.
The lower end St. Croixs are getting harder to come by as the fall run is upon us.
