My 'Baldans Kaleidoscope Golden Treasure' (not sure if it is the same thing as BK or a cultivar of BK) is like that too. I have it in an 8" pot and its roots are already climbing out in escape.
I also have a big pink-blush unnamed phal that is well on its way to great stature, too. The flower spikes are very strong and trying to train them up straight rather than letting them go sideways is a challenge.
I moved a restraining clip from the bottom (those little hair clip thingies) and the next day the stem broke from its own attempt to move the way it wanted. Even now it is trying to spike and it seems to buck against the stake at every point.
I'll have to look at the mounting of orchids. I've never done that. I prefer plastic pots and small bark mix, but I'm always up to experiment.
I bet I can find lots of infomation on this forum for that technique.
