I'm inclined to agree with BackPacker that you'd need very long, very strong arms to get an inverted stall out of the 2160.. however, there is some truth in the concept that coming around the latter part of a stall turn you have a pretty good control setup for an inverted spin entry; forward and out stick, with in-rudder. Scuttlebut suggests that the pitts likes to spin out of there, though I've never met the tendancy... could well just be people winding me up
