Bruce,

This question is an excellent candidate for an engineering approach to the
problem, i.e. try it and see.  The collective sense of the list is that
you'll see no performance issues, but perhaps you could actually model each
scenario, benchmark them and report the results back.  Run each model 1000
times or so to make the statistics more valid.  Be sure to do a CLRPOOL for
each run to be sure that subsequent runs are not using cached data.  Who
knows?  Perhaps the collective wisdom needs to be re-evaluated?
