From 1/4 oz all the way to 1oz. Has many uses. I use these in my tube baits as it gives the appearance and added attraction of a larger head (and it always lands hook up) just as the smallmouths favorite meal..the goby. Can also be used for grubs or creature style baits and so on. Pro tip...I will go as big as 1/2 oz in the tubes, to help insert into tube I will use some sent gel, like a smelly jelly on the tips of the football shape to act as a lube to help get it into the tube. Made with 4/0 LIL Nasty hook. With much exerimentation over the last couple years, this hook proves to keep the bass/fish pinned and not be thrown as easily as others and are super sharp.
