Pretty confident I've never seen this from a cradle. But I'd say, even if it is (sometimes) possible, I don't think this is worth working on. It's impossibly tight, and ball is out of control every time you miss. Figure out the safest way to get it to the right flipper: post pass, shatz, backhand left ramp, or shoot the scoop.

To add more: just because something is technically possible doesn't mean you should spend time trying make it repeatable. I somehow hit the right orbit cleanly from the upper left flipper once. No point in working on that!

But then again, I've never tried backhanding Quorra from a cradle. Probably because it looks impossible, and I've never seen anyone do it. But I have done it from the tip of the flipper. If I had no way to reliably get it to the right flipper, I might consider attempting it, but even then I'd probably shoot the disc and then drop catch on the right or bounce pass over to the right.
