You can use a #2 or #4 for any of these. All hooks have their pro's and con's. Sickle has a wider gap than most (especially an Eagle Claw) In my opinion, they are weaker and bend easier than most. Very sharp. Fairly inexpensive. Use a triangular file and touch up the point and you're good to go. Will straigthen out when hung up easier than most.

I poured about 300 a little over a week ago. I use both a #2 & 4 for 1/16. I fish weedless w/a Y guard and I like the #4 for the real brushy spots and the #2 for more open cover. I've heard the red ones are a little easier to break but haven't used enough to know is that's true or not.
