I am looking to incorporate some trolling wire in some of my tying patterns. I am going to use it for weedguards as well as to tie some tandem hook designs such as eels. Now, I have seen recommendations for #5 and #7 trolling wire. Having no experience at all with trolling wire, I was wondering if anyone would know if that is the test poundage or the wire gauge or what exactly. A few google searches produced no good answers. Can anyone give me the skinny on trolling wire?

Thanks,

Keith
