No, backflip are overrated. An olie is to skaterboarding is poping on skis.
Want so great advice? dont do it.Why?
1.You will get you ticket revoked
2.If its your first, you will either over spin and crash on your neck or underspin and land on your head.
3.the park hits are waaaaaay to icy.
If you want to learn how to flip:
1.Joind a mogul team, the coaches have experience with flips.
2.work on water ramps, the injuries are less extensive.
I know hnow to flip. I will never do them in a park. I have a mesured jump and qualified coaches beside me.
Even if I dont flip, I have a great time in the park, practicing bigger spins. they will not causeas much injury if I fall.
Here is a pic if you dont believe me:
