Default Slow fly or thin electric prop?

Any rule of thumb on when a thin "E" prop should be used versus a slow fly one? I pretty much use what the model manufacturer recommends but can they be interchanged without any problems?

As soon as your rpm approach the safe limit for APC SF (65000rpm/diameter) you need to use "E" props. Also be aware that APC SF suck a LOT more amps than the equivalent sized APC E.

I thought it was the other way around. Guess I'm going to have to go do some checking with different props.
