I prefer not to use either, i find that on the waters i fish that when you use silicone the carp can use it as an anchor point to blow the bait out of their mouth and rig rings aren't much better, i especially seem to get a few tangles and sometimes having the bait impaled on the hook when i reel in, and when you leave your baits out for anything up to 48 hours this can extract the urine a bit. all i use is a longish (around 3mm from the bait to the bend of the hook) supple hair and to stop tangles i tie the hair to the shank of the hook with pva tape or string.
