I think I answered this "where to put my thumb when playing the low E or B" in a previous thread someplace. Here is the usual disclaimer prior to my answering; Todd is the instructor and is often clearer in his explanations than I am so for definitive instruction BUY HIS DVDs and INSTRUCTIONALS (you won't be disappointed).
When I am playing the B (I play a seven) my thumb tends to float now just above usually swinging fairly free with my arm generally pearch against the top edge of my bass body. When I first adopted the technique (back in the dark ages) I had the same problem you folks are expressing. Back then I would often pearch on a pickup or rest my thumb against the body of the bass just above the B. Over time however, as my hands adjusted to FT and strengthened as I learned to strike harder without the support of a fixed anchor, I eventually and quite unconsiously stopped doing either and the thumb has floated free ever since.
The secret is playing the style as fully as possible but not letting some of the small stuff hang you up. I am a "if it works use it" kind of guy so even though I was only hitting maybe 75% percent of the value FT brought at first I plunged ahead modifying certain aspects of the technique to fix specific problems. Over time the organic nature of the technique will allow you to develop better and better ways to use it and your hand strength will improve sufficiently that you most likely will stop feeling the need to anchor.
I would also post this question in Todd's forum as I am sure he can give you additional insights you might find helpful.
