This is why I always use HH on the front and organic for the rear - power for one and sensitivity for the other. That's for a sporty road bike, though - I may reconsider for the XTR.

If there's no metal-to-metal contact, then squealing is most likely dust or pad vibration. If the anti-squeal shims are in place and in good condition, then a good clean and a bit of copper grease on the back of the pad as mentioned above is the answer. A smear is enough - you don't want it creeping to the braking surface.
