I have both - a Tempest and a Fury (4-blade). I use the Tempest in water temps <65*. Once the water gets warmer I switch to the Fury 4. The Fury gives me a solid hole shot under a load (I tournament fish) but I lose a bit if top end speed. It also makes it a bit easier managing the boat in ruff water (wind, lotsa boat wakes). The Tempest is a good top end speed prop and gives me a good hole shot in cooler water, even under a load.
If you're gonna w/ one prop I'd recommend the Fury.
