Keep selecting. Post a pic of that outstanding plant if you have time. I'd also love to hear from Frogleap.

Fusion - My plants from this cross were at a remote nursery (near La Crosse, WI), so I only saw plants a couple times during the season. I took final notes/selections yesterday. A record wet August help foster incredible Septoria and EB disease pressure on the nursery. At least half of the ~150 plants (10 different lines) were completely defoliated. Your line was definitely better than average in disease tolerance - but there wasn't a standout plant. The best plants in this line were comparable to the best in several of the other lines in the nursery. There was one stand-out plant in another line, by far best in nursery - tracing to a cross I made to another S. pimpinellifolium line you sent me a couple years ago (dark pigment phenotype).
