Frog Lotus has a nice studio -- I did a class there while visiting Mass MoCA.  Don't have a clue about the TT, however.  You can catch that controversial, overscale installation at Mass MoCA -- they just opened it over the artist's objections (six months late and way over budget).  Frog Lotus is one of those marvelous studios in a converted mill building, kind of like Yoga Vermont and some others.

The class I took was taught by the principal there (I don't recall her name), but it was a good vinyasa practice and fairly vigorous. A lot of quad work, as I recall it.  They do a number of TT's there, I think, and, to hazard a guess, I imagine you'll find it worthwhile.
