Unknown victory hexes & Captured units

[Embis]

Just looking at designing a scenario or two and was wondering how others might have used "unknown victory hexes"

can anyone point me to a scenario, either stock or home made, where these have been used?

What kind of situations might they be useful for?

I would quite like to design a scenario that is rather more than a "storm the position" and the use of some of these often underused features might add the spice I am looking for.

I am particularly looking at SBWW1 and was thinking of a trench raid scenario.
