Some experts I found easy were OceanWaves, GoldMinePK, SlimePK, and PowerpuffGirls. They all have a lot of easy parkour, but be warned, PowerpuffGirls has 4 neups (inclusing an invisible one).
Some insanes I found easy were ISS, Ancient, and BedroomPK. BedroomPK may be really long but the parkour is pretty basic and easy to get the hang of.
