Haven't used sickle hooks any but I sure like knowing that I free my jig (most of the time)by straightening out my little Aberdeen hook and bending it back. I even go to another level and heat the bend of the hook to make it straighten easier.
maybe my problem is that I get hung up more than I catch fish, but my jig poles and jigs fear no brush pile.

If if you ain't getting hung u ain't trying hard enough!!!
