I'll also go with two permanent poles. They will hold girls up to 350 pounds.
Now the next thing to overcome. There is QUITE the echo in this place because of the 12 1/2 foot ceilings. And probably not enough carpet now to break the sound bounce. When I rented the pole studio in the University District, the music sounded like crap because of the way it echoed. What do I need to do, in terms of setting up my sound system, to avoid that echo?
