Sv: TAE vs TBE

My impression was that TAE has less buffering capacity than TBE (even used
at 0.5X), and hence, cannot be reused as much.  If this is the case, you
might be ending up making TAE just as frequently!  Sounds to me like it
might be a toss up.  Incidentally, there is a section in Manniatis (or
rather the more recent addition whose first author I don't recall)
addressing the advantages and disadvantages of TBE, TAE, and TPE.
