When drawing the layout of spiral inductor with multiple metal layers connected in parallel, should the vias be placed everywhere or just at the ends? Thanks

The vias should be placed at the end points of the spirs.Otherwise, each via on the lines will create discontinuity and than these will increase RF resistances.
I assume the line widths are very narrow..
