ball busting set aside, the mks tours, track, stream, all of those are the exact same except for the lil edges. they all weigh the same, are the same size, i have the tours because the track's were sold out and they're all the same. i dont think adding "track" to it doesn't necessarily mean you need those over the others. dimension makes "track" pedals too, very similar to the mks sylvan tracks.

and as for toe cages, iunno people seem to like steel. they hold their shape and dont bend/get caught. leather straps are good too, but general consensus says the soma leather straps blow hard
