Sorry for not contributing (for good or bad 

 ) to this thread anymore, I really like the level of professional conversation and the sharing of facts and experiences around, by all those great people who have contributed to this thread. I have not lost interest in this topic, its just that I seemed to have lost it somewhere from the 5th page, I do not understand 75% of the metalurgical words tossed about 
  
  Still, interesting and very informative though.
