Turning props in on a Mystique
 

Here are my results:

Gets on plane better.
At cruising speed, needed a little less tab, but nothing significant.
When turning, rpm's stayed little more synchronized, and props seems to stay hooked up.
Top speed was the exact same, but was a little loose... not enough to sh** your pants, but not as stable.

I have the notched transom and running 31p bravos, labbed from mercury with some cup.
