I've heard of this maneuver, but usually it's done in a Cessna. Cirrus is a bad choice for a very questionable manuever. I'd never dream of doing it in a Piper, and didn't think about it in the Diamonds either. It really just isn't worth it. The only airplane I've flown that might have an option on is a T-41 due to it's impressive climb performance. But really you would turn crosswind before you would think to turn around so once again I just don't see the point in this kind of training.
