large batch transfer from 50 feet+?

I am going to start brewing 20 gallon batches and I'm trying to decide between using four carboys vs a conical 27 gallon fermenter. I would like to use a conical, but the room I could put it in is at least 50 feet from where the boil kettle would be outside, maybe 75. Has anyone ever pumped their wort that far? (It would be at the same level, but a long way nonetheless.) I could obviously use four carboys and carry them one at a time, but I'm curious how others who brew large batches handle this.

See what your pump is rated for.
And that's going to be some expensive silicone

I pump 50' with my regular old March pump. You don't need silicone hose.
