If you use two slots, which I think is a good idea, the adjustable miter bars are of much less use. What you need to do is space the runners correctly. Most of the adjustable bars attempt to center the bar in the slot. You can’t do that x2. You need asymmetric adjusting, depending on exactly how the runners go in the slots. One technique I saw in a video was to use paper shims to push the runners to the outside edges of the slots and then sand or scrape those edges if it was a bit too tight.

If you can find adjustable miter bars where you can push the bar to one side, and you arrange them so you are pushing the left one to the left and the right one to the right, then you could use that with a sled. I think a hardwood or UHMW runner is probably better for a sled.

I also think you want a front bar, but you could try it with just a beefy back support and see how it works.
