Here's how it's done. Using split ring pliers, remove the original hardware. I then replace all the split rings with heavy duty 5.5H split rings (100 lb. test) from NJ Tackle (http://www.njtackle.com/ ). Next, add a new set of hooks. I am using VMC 4X trebles, size 1/0, that I also purchased from NJ Tackle. That will do it. Since I have changed the hardware on my plugs, no problem with bent hooks or split rings.
I'm amazed that a big company like Daiwa did not realize their hardware was sub par on these plugs. Don't these guys test their products before putting them on the market?
