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

It wasn't that they copied a transbrake. LOTs of companies make transbrakes. Whoever the first developer was, lots of people have copied it. Screw up was having their guys copying a competitors stuff, NOT take the brand name off, and then either not noticing, or not caring enough to eat the product.
(Should have shipped them all back to China and had them mill the name off, and THEN sell em. )
Strange. Summit and Jegs have LOTS of Chinese stuff that they sell, with Summit or Jegs name on it. It usually costs more NOT to have the logo on it.
