Yepper, Scirocco Operator Class I for sure. (Owner and Operator are two
different things.) We are all working on Master Class as there is no
defined line to cross, it's a state of continued learning and passing on
what you learned. 

OT- Black Belts in Martial Arts came about because you had you White
Belt long enough to turn it black. Wasn't meant to signify _anything_.

If it was truly cracked you'd get the ol' flammable fountain of death.
