Is it wise to rotate the pot such that leaves don't "lean" too much?

[cythaenopsis]

I've been having some orchids in my plant collection for a good 8 years now, but I've never been quite certain about this one particular aspect: ORIENTATION to the light.

More specifically, where large leaf growth is concerned. For a potted phal orchid, I don't want the leaves to be notably tilted to one side. So my thought is, that it's a good idea to periodically rotate the pot 180 degrees to help "balance out" the leaves. Then once they're established and there's an active spike, keep the pot in one position through blooming.

Is that a good idea? Or does 180 degree rotation "stress" the plant?

And maybe an even more relevant question, is the fact that I'm experiencing leaf tilt meaning that the orchid is getting too much sunlight? Should I keep it out of direct sunlight altogether?
