sorry, i dont make these. I custom order specific heads for different uses. These are ment for small grubs, like the keitec spider or cabin creek small spider parts. I bought too many so id figure id sell or trade a few. I know alot of guys fish the keitech at least, these are a great head for them and you wont get mad if you loose them in the rocks like you would with a keitech super football.... trust me, lead vs. tungsten poly does not make a that big of a difference in size and sensitivity....you gota remeber tungsten jig heads are not solid tungsten like the bullet weights, they are tungsten powder suspended in an epoxy and spincast molded.....hence the melting effect if you try to bake pc paint on em
