I had to get a paperclip from the office to dig out the sliver of skin the pitot shaved off my forehead!
And I'm just beginning a conversion in the other direction: C152 to Warrior.
The manual flaps, fuel management and quadrant controls were the biggest differences I could see. I managed to operate the throttle friction instead of the carb heat on a go-around! Not easy to mix the two in a 152!
Good luck tp
