I've been using the Sickle siwash hooks this summer/fall with hootchies and bucktails. Largest size available was a 3/0. When fish were hooked, they stayed hooked. I understand 6/0 and 7/0 will be available by next year. I normally run a 6/0 Mustad on my gear with good hook-up ratios. The 3/0 seems to be a little small in the point/shank distance. The ones I was using rusted up in a week or so, but seemed to hold their point sharpness pretty well.
