Prop Selection 37 Outerlimits

Had new power built for my 37 outerlimits, I did have Bravo 1, 1:50 with HP 500's that dyno'd at 440 HP, ran about 76-78 GPS depending on load with 4 blade 28's bravos, new motors are 640HP NA have new XR's 1:50,. thoughts on 4 blade? v.s 5 blade? im going to start with 4 blade 32's, looking for input here, thanks guys.

400 HP add equals 4 inches of pitch on paper.
However, do it and let's see where the rpms fall.

OL's can perform better with more blades. Usually this is because of the ridiculous X dimentions. I like the 4 blades to start since they will be faster if they hook up well.

Let me know.
