Since I've been overly quiet (just moved, started a new job, wife and child still in transition, etc., etc.) I figured I'd throw in my $0.02 that someone else has probably already mentioned:
For met-con, I'd generally prefer lower skill exercises. Power Olympic stuff might qualify (particularly if the exercisee isn't hyperextending the lower back every rep ... ugh). But, I'd really prefer to see kipping pull-ups, explosive push-ups, tabata style (front in particular) squats, stuff with a heavy medicine ball, kettlebells, just about anything bodyweight (including low-intensity plyos: bounding, leaping, skipping, etc.), bag work, wrestling, and field work (sprints, agility, etc.).
