Series VII Protar, whether from CZ, B&L, Krauss, or Ross are still superlative lenses. Because each cell is 4 elements, cemented together, they have no trouble from flare. Surely, the new Cooke and Wisner sets are fine, but they are expensive. The Protars did well for Edw and Ansel and generations of shooters before us, they are still more than viable.
The Turner Reich convertibles are iffy: many were good, most were assembled poorly. The two strikes with TRs: huge numbers were made under gov't contract, the 5 cell design ( to avoid the Zeiss license fee ) made centering nearly impossible. Same problem with Goerz Pantars.
All Series III Dagors are good. These, IMHO, are your classic, and current, choices !
