The hook issue comes up here regularly, but search some of Roger Stephens advice on using tube flies and tinned hooks. I use the same hook on 90% of the patterns I tie now, and that a Gamakatsu SC 15, usually in a size 4. It's a light wire saltwater hook, but is tin plated instead of SS. I had an epiphany a couple of years ago after leaving a couple of flies on my console overnight. The SC15 was lying on a Targus SS hook, and in the morning the tinned model had started to rust where it touched the stainless steel. Not only do these hooks rust out quicker, but if you break off a fish on a tube fly, the bulky part falls away, leaving only the light wire hook behind, which presumably corrodes away quickly. And using 2x Fluoroflex (12.5 lb test), I don't break many off, even anchored in fast water here in the south sound. Get em in, get em off.
I think there are alot of people who have the misconception that you need to run light tippet in the saltwater. It's been more than a year since I've broken a fish off in the salt and that was a fat silver that took a big dive right when I had him next to the boat and broke my knot. I run 8 and 10 lb Maxima pretty exclusively and don't feel like I'm spooking any fish. I don't think there's any reason to fish anything much lighter.
As far as the size doesn't matter argument - it does to me! Not that I don't like catching the little guys, but I'm out there for the big fatties!
