The only way I know that you can get those big liplesses is know somebody or make them yourself. I just posted in the gallery some of my lipless masters that I created for molding. They all swam great and are between 1 and 1.5 ounces. I ended up leaving the business and sold the masters to another gentleman and he uses them quit a bit. You should try carving your own, they really are not that difficult to make, just copy a picture like I did.
Forgot to add that they are all between 4.5 and 5 inches long and take #2 trebles that will not tangle. They really are one of the easier baits to create but not many are doing it.
