agree with you that the old stuff was completely different and i prefer it, it hangs like iron and has a beautiful drape. but others may prefer the lighter and smoother looking new stuff. i guess part of the obsession with tonik was its history as a legendary cloth for mods and other cool Brits like Caine in Get Carter, but it was a really great cloth. It might have been the original, but there were other good 3ply mohairs back in the day, like Lesser's Lesslon or Scabal's Titan.
On mohair, anyone know of a proxy for Bateman & Ogden?
