What props do you use in what conditions?

I have :

a 12x16 stainless racing prop - This prop allows max RPM almost right away, If you have some super fatty's to pull up on slalom, this is a good idea.

13x13 Michigan Nibral - This is a good prop with a maximum speed of 48mph, good pulling. I have 2 of these because we have a shallow lake over a flooded town.

14x12 Michigan Nibral - This is a more powerful prop than the 13x13's, but less power than the 12x16

14x16 Michigan Nibral - My boat will hardly turn this prop at 4500ft elevation (Elephant Butte in New Mexico). You might think it would have low power and high speed, but it has low power and low speed, about 45mph max, but way less rpm. not sure on efficiency. This is a good prop for me at sea level though, 55mph top speed, so it is my fastest prop if you can get enough air.
