Gotta agree with the guy above me, locking turners are the way to go, the other guitarist in my band has a sick ass jackson, it has a locking nut on it (naturally because it has a floyd rose and the tuners keep it in tune well but aren't locking) but he took the screws right out of it because he hates having to undo it all whenever he wants to switch bewteen one major tuning to another, so I guess it depends on how often you're messing with what tuning it's in, but I perfer the locking tuners for convinence
