Mount or Re-pot?

[SamiSmith]

Thank you for the advice. I think I will stick to repotting the phal. I would like to change the medium a bit because the possibility of root rot scares me. I do enjoy the look of the mounted plants, are there any you all would suggest growing this way in the home. I live in southern Georgia, where we have high humidity throughout the year, hot summers and mild winters. What are some species, other than phals, that would thrive well in my environment? Thanks again!
