Well, I've made my own and I'm using them now. However, I don't recommend making the kind I made which are like this. It was time consuming, painful to the fingers, and generally a big pain in the a**. However, I did notice a *slight* improvement over the 12 gauge wire I was previously using (these cables are 10 gauge). Still, it was not enough to justify ever repeating the process again. Plus, they are big, heavy, and ugly regardless of the mesh covering I have on them. I don't know why I made them in the first place. I guess it was the challenge and curiosity...or just simply boredom and too much time on my hands.
