Awesome guide! It's helped me unlock three ESG so far.
I do have a question: You suggest using Peach+Mach Bike+Auto for Time Trials. Does the character really matter that much (like if I wanted to use another middle weight instead, I could..?) --- Kinopio is the ultimate video game character! Who else can drive a kart, host parties, play tennis, give good advice and items, and is almost always happy??
