It depends on how packed they are?
This is my method for creating long wave sliders:

The closer the pair of nodes is to the center, the further from the X-axis it goes. It takes a bit of eyeballing to get correct, same as spirals. The new single-axis scale feature (test builds) makes it easier to fit the size once they're made symmetric.
For very tight wiggles, use basic 4-point arcs, joined together with redpoints.
Edit: Are our minds nice and fucked? Good. These two sliders are the same:
