Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

Sorry I’ll call bull crap on this. Have you ever bought anything from Harbor freight.

Evaporust when it's on sale, but that's already made here.

Again, if the argument is no one can buy 100% American so you might as well not buy American at all, then that's silly
