It may be differences in design or design tolerances that are causing you the problem.  I have heard before that Frequency is a very good toric lens.  (Apparently B&L make better progressives but that's beside the point).  As usual with these things it's best to speak to your eye doctor.  It could be as you say that the B&L lens just doesn't work for you.
