Quality elevated rails

[simo299m]

TL;DR
Quality elevated rails so they can support more rails before it needs a support

What?
Rail support quality. like by 2 rail per level of quality

Why?
i feel the gap for elevated rails where it needs support is a little too little, but i can see why some of it make sense. but also i feel this is a good way to do it, as now there is a reason to get quality elevated rail support.
