Vibration is a lot less and great holeshots. I was able to save another gallon per hour.
Can't find on the internet the difference between Bravo and Mirage props. Someone says the Mirage is a cupped Bravo. My Bravos appeared to be cupped. My Bravo 4 blade appears to be cupped as well. When I get a chance I will attached pictures of the props.

Careful with your 4 blade. It may give you the best overall performance however it may provide too much grip and not enough slip. You may end up blowing your drive faster.
Just a heads up.
