You can’t steer in the air anyway :)
I’d rather land rear wheel first than go over the bars. Maybe irrelevant for the type of riding you’re both talking about
Tell that to anyone that lives for air time. You can by swinging the momentum of the bike. You can even lock a certain wheel in the air to use the inertia to change angle a fair bit.
Not really. You can’t steer the bike with the front wheel off the ground.
Unless you are super skilled. In which case do what you like :)
