Whats the difference, Which do i need for senkos, brush hogs, and other soft plastics?

Offset shank just refers to the offset or bend that holds the worm. An offset point means the point of the hook is off to one side so it isn't even with the hook shank. A round bend hook is just that, the bend on the hook is round which is a typical worm hook. A gamakatsu offset shank round bend hook is the same as a Gamakatsu offset shank hook, the only difference is one description takes it a bit further and tells you it is a round bend while the other does not. If it was different it would be described as an offset shank EWG or O'Shaughnessy or Sproat, the fact the description says nothing tells me it is a round bend. So unless there is something you didn't add to the "offset shank", I'd say there isn't any difference and if is just one description tells you it is a round bend while the other assumes you know. The round bend will work for all soft plastics but for thicker plastics some guys prefer EWG (Extra wide gap) or straight shank heavy hooks.  

not much. i use both.

There are so many choices now days that it gets confusing . The rule of thumb is to use a hook that has a bite at least twice the diameter of the bait . I prefer a offset roundbend most of the time others use EWG's exclusively . For most fishing I'll choose a hook slightly bigger than twice the width .

 

It was a lot simpler when I started out .
