repotting Neostylis

[tinarae]

I bought a Neostylis in bloom. Now that it's done blooming, I'm thinking maybe it's time to repot. It's in a deep 2" plastic pot, deeper than any 2" or 4" pots I have. Roots are coming out of the bottom holes, which is why I thought repotting might be a good idea. I popped it out of the pot today, and the roots all look very healthy, but very crowded in there. Should I spread them out more in a 4" pot, or does it like being closely confined like that?
