Zygo repotting options

[2Barefeet]

Got this for Valentine's Day. I'm a reasonably experienced orchid grower, but I rarely stray outside of the Vanda or Cattleya alliances. I know enough to know this is a Zygo of some kind (PLEASE correct me if I'm wrong, it didn't come with a tag), but from what I've read so far, what it needs is way outside of what I'm used to. I plan to repot as soon as it finishes blooming, but I'm not sure what to use. I'm not really set up to grow this guy, my greenhouse is set up for Vandas, high light, warm temps, and automated daily watering. I'd like to hang it up in a basket as it is already a fairly large plant, but I'm thinking S/H is the only thing that will work for my conditions. I prefer media that doesn't break down, mostly because I tend to kill stuff in bark. Also if I pot it, I can set it on the floor by one of my vents where it will get cooler temps. Thoughts? This one is currently hanging over the edges of a 4 inch pot, so I'm thinking about an 8 inch pot. And how often and how much fertilizer do they need?
