Rolling Road

[doublereefed]

I'm making a rolling road for my Allen Mogul. Are there best practices or collective experience on how to space the rollers underneath the driver? There are clearly physical limits, but wondering if 25% (of driver overall width/diameter) either way of the center point (where rail contact normally would be) would work? Too much?

There are a couple existing threads asking the same question. Should provide some ideas of what others have done. Links below.
