  Various properties of heavy-light mesons are determined, including decay
constants, the $B_{B}$-parameter, and the Isgur-Wise function. The heavy
(bottom) quark is simulated with the static, NRQCD and/or (fixed-velocity)
lattice-HQET effective theories, using optimally-smeared sources as produced by
the ``Maximal Operator Smearing Technique''.
