though i think you maintain energy better with high rpm while climbing or turning

That's more or less true and the way it should be.

Pitch is like changing gears in a car. If you use high RPM it's like cruising on 3rd gear or something, if you use lower RPM it's like doing the same on 5th gear: it will be faster when driving straight or downhill (level flight and dives), but the amount of "pull" you get is not enough to drive uphill if you happen to not have a lot of initial speed (climbs).

In other words there is no magic prop pitch and RPM setting for all circumstances, you need to be constantly adjusting it depending on what you're doing, as long as you don't exceed the useful power band (too low or too high RPM is not useful and can even cause damage, i usually vary between 2200 and 2500 RPM).
