Oncidium repot or ......

[The Orchidist]

I have an older mature plant looks like its a few years old and has about 8 bulbs that have spiked a few times over the years , the leaves and everything about the plant look fantastic with some leaves standing straight up 12 " high
when i took out the clump to repot , the roots are so clumped together and compressed , i was unsure if i should pull the stuffing out from the centre , so i just took the mass clump and put into larger pot and used fresh bark and coconut husk..

Should i have taken the time to separate all the roots and flush them , I feared of breaking them . or keep it the way i potted it and hope the roots will expand out in its new media ?.. or perhaps i should seperate plant in sections and use 2 pots instead of one .

thanks for your response ...
