The Towering phalaenopsis - trim or not trim?

[Jawfish]

My phalaenopsis is 7-8 years old now. I am wondering what is the usual action at this point for most people. Leave it as is (after trimming off the dead stem from the last bloom and a few dead roots) or cut off the top and repot just for improved looks? I just removed it's baby from this side earlier today. The older leaves are really long and the whole plant leans.
