I was lucky enough to find four Panaracer Magic NOS tires in Andorra a while back.
They're fantastic, very focused on hard terrain with loose stones.
The more the insoles, the more ball they grip (they round out, not flatten), and that makes them fast, very fast.
They're from the era when Panaracer had fairly soft durometers, providing a very solid and optimized grip. They're not as soft as the Duster Pro, but they're as soft as the Smoke with a skin sidewall, but with a lower lug, they last less.
Thank God, I don't use them much, and they'll last a long time.
