600 Question regarding multi-blade heads

[DAL2855]

I am getting ready to start the build soon on my 600 class Nitro bird, and I am wondering if I go with the 4 or 5 bladed head, should I consider going with 550 blades instead of the 600 blades? I plan on installing an MD-500 fuselage on it, and for scale look I want to use the multi-blade head. But dunno about which set of blades to use on it. Which ones will be better for scale type flying?

Check out Cliffs shop Home - RC Aerodyne | Scale RC Helicopters, Airplanes & Parts Store
They are the experts with scale builds, and have scale blades as well.
They also sell scale mechanics for builds to hide the frame for builds like the Huey. You can see right through the fuse like a real one with no sign of the mechanics. My 600 comes from them. They have first class customer service.

They are actually who I am planning on getting my Head and Fuselage kit from for this build!
