Tracy -
I enjoyed the article immensely! I've tried three different instructors so far. One was on my retreat at Kripalu and I liked her a lot. That's expensive though. The second was a six-session freebie I won at a studio's grand opening. I liked her but it's too far to go often. The third was my local gym. I *loved* that teacher and went every week, but she eventually gave it up to work elsewhere. So I suppose technically I did try her replacement for 2 sessions but the replacement was too "harsh" for me.
So now I'm back to just doing it on my own
