This discussion reminds me of a Bible verse. I know I\'m using this out of context, but it goes, \"All things are lawful for me, but not all things are profitable. All things are lawful for me, but I will not be mastered by anything.\" (I Corinth. 6:12)
The application is this: whether we are perfecting the existing varieties or creating new - is our work in the best long term interest of the breed and of our time and resources invested? Count the cost. Will our work prove to be \"profitable?\" We might ask ourselves \"Do we have a hobby, or does the hobby have us?\" Merry Christmas!
