Really Racing Maniac??? I would have expected an Engineer to know this already....

That said the Guarder Black rubbers are 70 IIRC while the Guarder Clear are 50.

I personally use a Guarder black in my ~390 FPS rifle with good results. Haven't done comparative/quantitative testing but I like it. I'm assuming that there's some overlap between effectiveness vs FPS so unless you're using a Prommy red in a 270 FPS setup or a prommy purple in a 550 FPS setup I wouldn't worry about it too much. My own personal cutoff is softer rubbers for sub 400 and harder rubbers for over 380 (taking into account the overlap I mentioned) I wouldn't use a hard rubber below 360 FPS or a soft rubber over 430 FPS.
