Mytiju...if you scroll back through the archives, their were a few threads by Togmaster and Rodbuilder on what size tip should be used when fishing many of these areas.
For the bight, when fishing water to 80ft, go with a 11-12 tip.
Highlands reef, you can use the sizes mentioned also since the majority of the fishing will be in waters 50-65 feet.
When fishing waters such as New Grounds and 17 fathoms, you should use 12-14 tip rod, with a 13 tip the best all around size, especially if you have to use a heavy sinker.
The newer MB1143F blanks have a somewhat thinner inner wall, so what may have been used in the past, must be taken up one tip size. The length should be from 7'3" to 7'6" depending on how long a foregrip you are comfortable with.
