Hi Gib,
there's another thread with the soft fold boo boo where fabao also shows a soft curl proof as recessive to soft fold boo boo

However, Saga's charts needs 2 proofs before they will show something so if you could send your chart to them, it would be very helpful. Then they can show the placement of between soft fold boo boo ears between ORF and soft curl. (Fabao's trait chart already shows that but it would be good if Saga's did as well)
