Cheerleading or Dance Team?

So I'm in the marching band and I play flute but I want to try something new. I wanted to be a cheerleader ever since I was little. My high school requires a round off with 3 backhand springs. I have a round off,cartwheel,but I haven't done my backhand spring in a while. My mom doesn't want me to do it. She said I could break something and I'm above that. I haven't took any dance so I would be a beginner but it seems cool and I catch on quick. I also have friends on dance team that can help me. I would love to learn dances!,but I'm scared to dance on the field during half time. My mom likes Dance Team so I can do concert band. Which one sounds like I can do better? I can't do both!
