What's wrong with instructing? It will certainly give you those "stick and rudder" skills discussed, that is if you wish to survive your students. It is certainly better than dozzing off as a P2, doing the gear jerker and radio parrot thing. Those P2 hours, won't teach you a thing; just fluff a logbook, that your skills won't be able to justify in front of a perspective employer. Which will you go for? Quality or quantity? Be wise in your choice!
