That's really strange, I wonder Yukon if you could have just gotten a bad batch of hooks. I know at times manufacturers will get a poor run of metal that can lead to these kinds of problems. I generally run about a 3/0 gami siwash on the back with my drag set light on the strike and then tighten once he's hooked and have never had a problem with a siwash. The gami siwash are mean hooks but now you have me thinking.
