Jeff, with my 150 there is no way to flip the prop without wrapping fingers around the blade. Not really an issue as the engine is tuned well and I have a couple thousand flights of familiarity with a DA 150. You've seen me start it up it's not a big deal at all. Some guys who simply seem to know everything and want to continue to struggle, tell others what to do and resort to name calling can just continue to do so. I'm happy to go fly and burn a couple gallons of gas as they struggle to get an engine running, no sweat off my nose.
