60 heavy 64 light on the 3 blade tempest
58 heavy 62 light with the 4 blade rev4
The tempest is a Lil faster on the top, but the rev 4 is faster out of the hole, holds better in turns, and will stay up on plane at slower speeds if your running the shallows looking for reds!
Both do good on fuel economy, and the tempest is no slouch either, the 4 just has a Lil more bite and grab to it!
