Guitar Neck CAM - straight or round nose bit?

Hi all, hoping for some advice on the best way to machine the back of this guitar neck, including the heel. See picture.

 

I've read that a round nose bit it best for finishing? Is that true? The problem is that if I use a round nose, I've got to cut deeper on the

sides where it meets the spoilboard to get a nice straight edge. However, I also still need to use a straight bit to clear the junction

where the heel meets the finger board cantilever. So why not just go ahead and do the whole thing with a straight bit? (I'm finding

it difficult to restrict the cam to just that area and still get it to cut into the angle). Can I get a nice finish doing that? Should it just be tiny stepovers? 

 

For that matter, would the stepovers be any different on round nose vs. straight?

 

Hoping that  can chime in here since he recently did the 3D guitar demo with CNCRouterParts.

 

Thanks.
