dextersp1.... I took an abbreviated 1day class from Bill and Christy way back in the mid 80's, prior to his developing his pneumatic system... he introduced me to the mental reward concept with instantaneous feedback derived from shooting white painted steel targets... IIRC he started putting the pneumatic moving targets together around 87.....his targets prior to that was a 3/8 inch steel IPSC silhouette 16x24 with the shoulders cut away leaving a 6x6 head.. a "U" channel welded to the back and 3 pieces of 1/2in rebar bent with a slight dog leg to fit into the box channel provided a tripod... the whole thing easily transported by a hand truck....take a gallon of cheap white house paint, roll paint the target... shoot no more than a magazine... repaint target... by the time you use up the gallon of housepaint, you have a pretty good idea of what you are doing with your practice drills
Bill is an excellent teacher, and really understands the mental aspect of shooting.... since Sept 11 has been busy doing a lot of work with SOF shooters... to answer your question, no , I haven't talked to him in quite a few years and did not take a recent course
Zack/dexter...check out the Area 6 USPSA web page for the address of South River Gun Club, between McDonough and Conyers....I'm sure they can answer your questions for local instructors and provide feed back from recent attendees
