Should I use nylon rollers or steel?

Question

is it better to use Nylon rollers than steel if I install the rail cap. My old steel rollers on the aluminum rail makes a black dust as it wears

I understand what you are saying about the dust, but I still prefer the steel roller. I don't think the nylon rollers will hold up as well. In fact, you might end up replacing the nylon rollers far sooner.
