If you can't handle a certain slope, apply good judgement, be safe, be safe to other's, and take your time.
All of us have jumped into runs we couldn't handle at the time. That's how you learn to handle them. Most of us survived the experience, and hopefully didn't endanger or injure anyone else.
My 10th day skiing EVER, rode Chute75, the Face, OlympicLady, RedDog, Cornice, Slot, and Headwall.
My 8th day, the best I could do was sideslip down Siberia's bowl, taking maybe 20 minutes to finish. Still had trouble at Shirley the day after.
We all have to jump in with both feet sometime.
