One thing is for sure...I keep all my pahls in s/h and last summer I switched my cymbidium to s/h as well. It loves it! As long as you have the conditions to bloom it, it drowns the s/h medium in roots. Phals are a bit more conserverative, but like it as well. The seedlings are difficult to find the proper place for them, ie somewhere between wet and dry, because there is less medium and the water evaporates more quickly. I'm waiting for an oncidium and a belleara to finish blooming, then they'll go s/h too.
If you repot now (in the winter)...let's just say it's going to be a test of patience for you.
