Catorce14:
PukinDog gave an excellent appraisal of your ideas.
I would add just one more thing: pilot handling skills are perishable, and if people do not get enough flying, their skills degrade. How much is enough? Certainly 100-150 hr per year is not enough for people to be always at the top of their game. Actually, the number of sectors is more important than hours - the demanding bits are take-off and departure, descent, approach, and landing. The level cruise bit does not add a whole lot to skills.
I suggest a sensible minimum for a crew is around 5-10 sectors per month to maintain a good skill level. Your planned utilisation seems to be well below that.
Think about this: you and your family are on board, your pilots have flown twice in the last month, and tonight you are heading into a difficult field, short runway, poor weather, crosswind near the limit.
Is that where you really want to be?
