As someone who does not pole at home (until my living arrangements change), I am deeply unhappy with studio learning. Although I feel that I have had quality instruction, I'm also painfully aware that I've already spent about $550 on lessons at one studio and have already committed to $200 in lessons and a $100 Karol Helms workshop at a new studio.
I realize for less than half of the money I have spent thus far on instruction, I could own my own pole and practice for free as often as I want. For all that money I've spent thus far, I've gotten an average 4 hours a MONTH of practice. My studio has stainless steel poles that don't spin, but at my snail's pace of classes, progress is so painfully slow I'd never even be ready to start learning spin. At this point I'd rather transition to self-guided practices with DVDs and Studio Veena, but open pole sessions run $15/hour at one local studio, is only scheduled once a week at that, and is often canceled.
Just something to think about. If you like burning cash, never feeling like you can get enough practice time, being watched by less advanced students, and being constrained to a limited diet of moves without the creativity to experiment and try cool moves you've seen and to free dance, going to a studio may be for you.
