You should be able to switch between using RTTI and using ID's in the 
dispatcher with
a few lines of code.  *Measure the difference* before making decisions

Of course, if you need the ID's around anyway for other reasons, they are
not a problem.  I wouldn't expend Herculean efforts to eliminate them.
