I bought this one, too, and it is quite vigorous so you should be alright.
I never could get the watering right with orchids, either. I would pot them up rootless in the spring and, by next spring, be rootless again. One day at the local gardening store, I saw the lava rock, realized that orchids don't really need 'soil', and I have been using it ever since (except for the Nelly Isler, Bulbophyllum and Pleurothallidinae which get moss).
This has walkeriana in it so it will like to dry out very quickly in cooler weather and have more water in the summer (but still have plenty of air to the roots).
When transplanting the Cattleya, I waited until I saw new growth then soaked it well in distilled water for an hour, gently removed the medium, then held it in the new basket pot and carefully put the dry rock around the roots. I kept it dry for a few days to let the roots heal and haven't moved it until just today when I adjusted it in the pot as the new growth was at the edge. I noticed that some of the roots had sent out new green growth...which I might have harmed with the adjustment (I will let it dry for a few days, now). New pseudobulbs will be putting out new roots soon so I am not too worried.
It is best to keep them still until the roots have a chance to keep the orchid from wriggling. Sometimes, wiring or staking the orchid in the pot is necessary.
Good luck!

Mine seemed to have them when I first received the orchids but I don't see them now (I just looked). Not sure what they were.
