Hi guys...

To tell the truth, I didn't expect this thread to go so long !

I'm really enjoying some of the info being posted here. This exchange of experiences, IMHO, is really worthy.

As some might have noticed, english isn't my first language, so, please, be patient with my grammar mistakes.

Boeing says that VNAV has overspeed protection, so, as far as I understand, the pitch mode should revert to a more conservative mode before the activation of the clacker.

Anyway, I feel myself more comfortable (and the passengers probably feel the same) using V/S or LVL CHG to dive and recapture the calculated path. Sometimes I even go a little bit under the path in order to trade the excess of energy for altitude. But all that depends on the guy sitting on the left seat !

Some of the "VNAV maniacs" don't feel like this being a "good practice", but it often works and avoids the excessive usage of speedbrakes.

Cheers,
