I wouldnt think the Timmy Boy's are as light as the on dunes arms being's the on dune arms are shorter. But I dont think you can just outright buy lightweight spindles that will accomodate the spindle mount wheels. They can be custom made for a small fee, Im quite sure.

I have a set of Fox Floats, brand new 18.25", they are very light, 2.8lbs each.
