Logitech driving wheel pedals hack: which squash ball type/color?

[mickael28]

I read in several places that one can try putting a squash ball inside the pedals of the logitech wheels (GT or Pro) models and this would offer some resistance when pressing them.

I've now seen that there are 4 type of squas balls:

Anyone knows which one is better to offer more resistance:
 * Black two dots
 * Black one dot
 * Red dot
 * Blue dot
?

The listing you linked to says it is the lowest bouncing ball of the four. I would think that the softer ball would bounce less than the stiffer ones (maybe not!). I don't know if softer is better though for your purpose. Interesting idea.

It's kind of a crappy ad. I'd assume that the "intro" ball would be softer and slower/less bounce ball, while the "Pro" is the harder and faster one.
