Well I received my prop and installed it today. I decided to try it as is before I raise it up 2 holes. It was really windy but here's my first impression of the prop.

It was difficult to tell if there was improvement in hole shot because it felt so close to my old prop. It may have a slight edge. Bow rise was about the same as well which was never really a problem so were good there. I tried to look at the splash line the best I could to determine if I was getting any more lift from the prop. It did not seem to provide much lift at cruising in comparison but at wide open throttle and trimmed out to the same level as my 3 blade the splash line was further back. Again I think there was improvement but was difficult by the seat of the pants testing. Plus I went to a short lake so it made even more difficult to get a good feel.

There was a lot more grip as far as cornering. It actually was scary how sharp the boat would turn now. I could also slow down and hold plan better (down to 3600rpm but it begins to lug some) so I'm going in the right direction.

here's a few performance specs.
27.7 @ 4200
31.7 @ 4800
33 @ 5000
40.5 @ 6000

I was glad to see that this prop still maintained good speeds. Almost identical to my 3 blade but a touch better in the mid-rpm range. Which I guess tells me that I must be getting some lift. Even though it was really similar to my current prop I am excited by the potential. I know this prop will react better to raising my motor than my Solas 3 Blade. Torque steer was not bad at all and once trimmed out it almost went away. I assume once I raise the motor that will take out a little more and then I can fine tune with the trim tab from there.

The prop does not have any vent holes and on the PT website they recommend 5/16" port. After I raise the motor and see how it performs maybe this would be another option to get an even better hole shot.

So what do you think so far Steve? Heading in the right direction maybe.
