I completely agree. Don't expect that you will be able to breed SSS grades from them alone for at least a year or two. minimum! Depending on the genes you may never especially if you only have one tank...S+ to get to SS or hinomaru is not that difficult. It may take a few generations or you could get lucky and get a couple hinos out of the first batch. But to get to anything higher (SSS) would take an extremely long time.
