I have to agree with some of those who are pro-sharing. I'm in L.A. and go to a wonderful studio in the Santa Monica area. There are five poles, 3 stationary, and 2 rotating and the classes are booked at no more than 10, although the further the classes progress the number usually drops as students drop the class. I have had the opportunity a handful of times now to have a pole of my own, and honestly I prefer to share. There are two main reasons for this.
1) My class is super intensive. The class is 1.5 hours long - with a heavy emphasis on a 45 minute warm-up, stretching, and strength and toning exercises...specifically in abs and upper arms. 45 minutes on the pole for me (espeically with the current content of the class) is just far to long to be hauling my ass over my head over and over.
2) We are taught a lot of tricks that I am uncomfortable performing alone for the first few times. In classes were we had enough poles for each girl to have one, we ended up teaming up in twos for spotting anyhow.
I also think that one of the great things about my pole studio is that a class levels together. We always have the same instructor, the same time slot, and the same girls in our class. We do our 8 weeks together and move to the next level together. This has allowed our small group of women to become really close with each other, and very supportive, even outside of class. So I guess for me, I cheerfully share because it's a chance for me to cheer on a fellow classmate, learn from them and sometimes help them learn something, and to be supported and spotted by a classmate I have grown close with and trust, an important factor to me when trying new flying tricks.
Besides all that, at the end of class we split up into smaller groups - usually 2 or 3 and have the opportunity to free dance to a song of the groups choice while the other groups cheer on. We have the chance to get out of our head and be a star in our own show without worrying about be in someone else's space.
I adore our class set-up and wouldn't change it for the world.
