What a diameter change will do for what they are recommending is to increase the contact area of the prop fins with the water. With more water contact, you gain friction between the water and the blade (this causes the rpms to go down) but that friction also means the prop will stay "hooked up" better in the water, resulting in the prop having a better ability to hold the bow up with less trim angle.
No matter what, I'd suggest getting out on the water with a bunch of different props in combinations of diameter and pitch. Spend some time making runs, turns, etc and see which one does the best job. Then...start playing with motor height. For some people, they enjoy this type of work...others, not so much... In the end, though...you will be much happier since the boat will perform the way you'd like it to..
