100% Root Loss Repotting

[sabina88]

I just got this new guy today, banfieldara gilded tower 'mystic maze'. I had a feeling the roots would be bad but when I unpotted it, low and behold 0 roots. Thankfully the new grow is just starting to put out roots so it should recover quickly. Anyways, my question pertains to the oldest pseudobulb (the one with no leaves for reference). When I was removing the dead roots it was a bit wiggly and I kind of feel like I could easily remove it by hand. But because there's so few pseudobulbs, and their so shriveled I wasn't sure if I should keep it on for now. So my question is, should I leave it until it reestablishes itself better or do you think i'm ok to just remove it now at this point?
