98% of the jigs I sell are done in sickle hooks. Once guys switch, they usually don't go back. Only issue with a sickle hook (At least with Matzuo) is that they are chemically sharpened. In other words, IF for some strange reason, your hook gets dull, bend the point, or whatever, you pretty much slap on a new one as they don't file all that well.
As for bending them out. We have seen it go both ways. On the bigger jigs (up to 1 oz) and using 4/0 hooks, they have a tendency to break rather than bend. But, when you are fishing very rocky bottoms for walleye and are used to snagging up on the bottom a lot, no one really cares if you lose them or not!
On my smaller jigs (1/32, 1/16, 1/8oz variety) they do tend to bend a little easier and can be bent back. I usually sell red, black, and bronze and don't see a difference in the color. Many of my customers were dead set on the red hooks (for some reason). That was until I showed them (in the instance of walleye fishing) only 1/4 inch of the hook is visible when hooked in plastic. Most of them now like the black chrome!
