Cork vs. Tree fern for mounts...?

[boytjie]

Hello all! I have a Brassavola Nodosa 'Gale' that is thriving, but is outgrowing its mount quickly and needs to be remounted. It's currently growing on a tiny piece of tree fern, and I'm considering switching it to a cork slab, which looks more natural and doesn't break down as quicky, IMHO. Before I do this, any thoughts as to why changing over may or may not be a good idea? i.e., Do tree fern or cork have any obvious advantages over each other as mounting material? Thanks!
