I see wire up to .062 for musky spinners but some in the .052 as well, I never saw any in the .041, that is more of a wire diameter used for bass. That said, most love the twist tech but I haven't been able to find a die that goes over .041 and everyone I know that makes Musky bucktails and such all use the boggs, so I think if you want to get into making Musky sized spinners you have to get the boggs.
