Damn... I've near done that a couple of times, minus the leg in the hole trick that does up the anti a touch. But had several occasions where I've taken the wrong ridge and it's turned a half hour walk into a bloody multi-hour jungle bash up and down cliffs etc. Never needed PLB but was rooted at the end of them and needed a few days licking the pride and recovering. Nowadays it's a GPS with hansel and gretel feature engaged and waypoints pinged at pertinent places. Worth the hassle.
