Hi Eric, as we already discussed in Rome, the whole set of analyses on the recoil of fully reconstructed Bs (i.e. Vub,Vcb,moments, b-> s gamma, b-> tau nu) would profit from option 2 (where I assume you plan to write out also the composites?) or 2a (this sounds really nice, is it really feasible?) thanks ric P.S. long time ago our effort was renamed from Garbage to SemiExclusive ...
