While I have seen my fair share of under and over indexed tables I am a wondering why this concern about slowing up an insert. Rarely is the problem with an application's performance related to speed of inserts. Rather it is the speed to retrieval, SELECT, that is the issue and the focus on getting the data IN should not take precedence over getting it back out.
One can only insert a record one time. Likely the record will be queried many many times thereafter.
