So, here's the rub. How do you solder a lead (leed) from a mosfet to such a heavy wire that will be about 6 or 7 inches long? Try it! Take a soldering iron and try it! It's tough.
For cryin' out loud, man! Find a piece of scrap copper tubing somewhere, pound it flat with your Oprah hammer, drill a few holes in it, and BOLT the wires you solder to the leads to the now flat copper strip...or something like that...

...or am I missing something here...
