Who is your go to character and what is your kart combination in Mario Kart 8?

I mainly use Rosalina with The Duke, Cyber Slick, and Bowser Kite. I use Blue chim ưng sometimes and also play as màu hồng, hồng vàng Peach, Cat Peach, and Shy Guy.
Whenever I play Battle mode, I use Baby Rosalina with Mr. Scooty. Cyber Slick, and Plane Glider
