should I swith my teble hooks over to siwash on my kwick fish? Or should I just switch to a nonfactory hook. what size and brand would be best for king salmon.

Lots of different answers to your question depending on when, where, and how you're fishing. My advice is to pick up a copy of the latest issue of Salmon/Trout/Steelheader. They have a very good article on exactly your question. The issue is on the newstands right now.
