I need smaller hooks for my roboworms and finesse worms, what is the difference between these 2?

O'Shaughnessy vs. round bend.

the o shug  has a shorter point to shaft distance and lighter wire the offset has a deeper bend and BETTER line of pull from eye to point of hook

o'shaughnessy is obviously irish. That's the only difference ;D

These work great , I even use the 4/0 with baby bush hawgs:

Is there a specific reason why you would choose one over the other?
