The BBS hooks use a heavier gauge wire ensuring you're able to last on a longer fight with bigger species, along with that the assist cord has a fluorocarbon core which gives you significantly more abrasion resistance than just the braided PE. These are excellent speed jigging hooks for longer knife jigs, meant to be fished on top. A single hook will generally be plenty but you can opt for two if you want.
These will work well for yellowtail, yellowfin and bluefin along with most other species that bite the vertical jigs on a fast retrieve. The point is round to make getting a hook set easier, while the shank of the hook is forged to provide strength. These also have a healthy barb compared to a lot of other jigging hooks which is nice to see.
