Do you have a rev limiter at 5500 rpm? It seems there should be an rpm difference between the 30 and 32's you ran. What speed and specific rpm are you getting with the 30 & 32's? We can look at the slip numbers to see what is going on. This will help determine whether a 5 blade will work better. Usually they do.

Speed numbers are required at the 5500 rpm level with both props to make a good assessment. The props should run similar rpm at WOT since the 32 I Labbed

However, 5 blades don't "usually" run better. That is a immature statement till we know more. Depending on the efficiency of the current props, who Labbed the 32 and to what recipe, it is impossible to say a 5 blade will be better on a f26.
Get some more info and we can better discuss the set up.

Thanks guys for responding headn out this coming weekend. Going to plug in the computer to make sure that the rev limiter isn't set at 5500. Also the speed was 97 mph at 5500 with the 32. Thanks again

19% slip is a little high.
We'll wait to hear back after more testing.
