Orchid position when i repot

[en3rmax]

Hi there,

Here is the latest picture of my orchid that i'm gonna repot, the medium looks ok in the pic but it has really broke down under the top layer.

My question is my phal has taken a more flat on the side position over time and is quite heavy and seem to like to rest on the side of the pot, when i repot her should i try to prop it up more or leave it in the position it's in now?



Here is the mix i'm gonna be using, i hope this is ok, it's medium and small grade douglas fir bark, sponge rock, and foam.



Thanku once again guys, i seem to be bombarding the board today :-)
