I suppose I'll lend my two cents about the FP.
Right, the Royal FP. What a wonder typewriter, I find its touch to be the best that I have ever used on a standard typewriter. It's light, responsive, and just doesn't seem to want to stop. As for the piling, I have 4 Royal manual standards and this one is about the same as all of the others. If I have an extra cup of coffee that day and am too quick and jittery, the FP will skip a space or pile. But that's only happened a few times.
The style is very contemporary, showing the shift from the 50's to the 60's nicely. The build quality is excellent, a hallmark of Royals. Though for how big it is, it is rather light; I was surprised when I first lifted it up and carried it from a garage to the trunk of my car. I repainted mine baby blue, because I figured I don't have any blue typewriter save for a single Olivetti Lettera 22 (and even that is more akin to a teal). The FP is easy to repaint, for all of the panels that were originally painted, come off rather easily. I even did the side panels because I wanted a little extra pop of color.
All in all, a wonderful typewriter, and represents the Royal line very nicely.
