We were impressed ourselves the same way. Your statement sounded like the F-14 were as heavy as the SF-71, when the SF-71 are in fact as light as the F-14, which are flow-formed.
When we first designed the SF-71 it took us about 3 months to tweak every single detail. Running dozens of hours in FEA to make them as light as possible yet certified to 1600lbs or 727kg. Light and strong and affordable. You can't beat that. The lip size, spoke thickness, spoke depth, concavity... everything affects the final weight. We did some very clever tweaks in the spokes that actually helps reduce the weight. Same tweaks you see on the HRE race wheels.
