Ever been a Black Belt and Switch Styles/Arts?

This was inspired from one of the other Martial Arts threads. Ever been a Black Belt and Switch Styles/Arts? I was a 4th degree old school Tae Kwon Do and I switched to Judo in 2001 and finally am up for a black belt after being on and off for the last 16 years.  Was it hard for you guys?  Did other instructors have a problem with your past or what you studied before?

I was a black belt in Judo, then I switched to Wang Chung and it was really fun.
