I agree with @1skinut
I am not a great skier by any means, but I don't even bother with 15 off anymore. Too slow, too much rope, and I'm too fat. The geometry of shorter lines really helps us bigger guys accelerate and keep moving. I start at 22/32.
As for free skiing at 32 off, 34 MPH, if you're taking video of yourself and are using that to correct and work on things like stack, hips over ankles, staying connected off the second wake, etc, I don't see why it'd hurt you. If you're just out there reinforcing bad habits, that's a different story.
