Coytee: Shouldn't you keep those in case you ever want to go back?

Yes, I had kept mine until recently....just in case. However, I now know I will never go back to the K401 horn after living with the Trachorns for a few months. I certainly don't plan on selling my Khorns, so I sold my K-401s last week.
