I've got a Little Giant 2-MDQ-SC, that has a max head of 14.6 feet.
The problem I'm encountering is a dead flow spot in the block. I'm aiming for a jet, but of course because of the unusual inlet geometry, I have to tune it all just right, to maximize what my pump can do.
I ran some tests with my pump, where I cap the outlet with caps with different size openings. I was originally shooting for 3/16. Right now, I'm looking at 1/4. I also tried a 3/8 test.
None of my tests were conclusive. Part of the reason is the calculation (missing measurement?) of the pressure drop. I also suspect that the pump is behaving erraticly, because it has a design limitation (i.e. it doesn't do 0 head), or maybe I'm just completely wrong and nothing has anything to do with anything...:shrug:
See LiquidRulez thread for a bit more info.

The pump may well do a 14 foot head but try to get a 14 foot head with a 3/16 id hose. Does that pump have the required pressure to push the water now in the same distance? It's the limitation of the impeller called back pressure.
