I had reservations about taking a 2-day course because I've taken several 3- & 4-day courses that I've recommended be extended a day. But the instructor had this PLL course "dialed-in" - 2 days was perfect; lots of excellent content and time for questions and discussion. I particularly related well and enjoyed his laid-back, casual teaching style and class interaction - WORLD CLASS! I learned a tremendous amount about PLL's! Most importantly, I now know that PLL design and theory is NOT "magic!" The class has definitely given me the information (and confidence) to design, build and test a PLL - mission accomplished.   E.S.
