I just picked up a set of Rev 4's in a 25P to test out on my Formula. So far I've tested a stock set of Bravo 26's. A Set of labbed 30 casting Bravos, repitched to 28 and diffuser removed and BBlades added a lot of cupping to the tips when they reworked them. I've also got a set of factory labbed Mirage 27's I'm going to test today.

I tested the REV4's on my boat last weekend, I didn't care for them. The boat felt glued to the water, I like the boat to feel loose. Speed wise, I didn't see and improvement over the bravo, hole shot and mid-range were all pretty similar to the bravo. Again, for me I didn't like the way the boat felt in 1'-2' chop. In big rollers in Lake Michigan the Bravo's were superior. With Bravo's my boat will land softly in a 3-4 roller, the Rev4 the boat rode more harsh.

Now my boat is running -2 sportmasters and ITS boxes, so this may attribute to why I didn't like the REV4. I know most guys with my hull like this prop.
