I have several hundred hours in my 600 I haven't had any " bad " stall spin experiences with mine. I fell out of a thermal one time into a spin because I was flying too slow for conditions, recovery was textbook and within one half of a turn. I find it relatively easy to fly, it climbs well in thermals. Circles at 50kts is best speed in thermals dry, I add 10kts to all numbers wet. It flies great wet. A true 50:1L/D with the 18m extensions.
