I have taken the Intro, Roll, and the Whitewater Weekend courses. They've all been informative, supportive, and fun. It has been a progressive learning process and I do like your emphaisis on offensive paddling rather than defensive paddling.  The Intro to Kayak (Level 1) class is a perfect foundation.  I am probably going to retake the Intro class because there was a lot in there that I just could not absorb at one time; WAY beyond an 'intro' class!
