more fun with jsessionid persistence

I am setting the persistence on the first server response for clients who disable cookies. For clients who enable cookies, is it better (read--more efficient) to persist them with cookie insert, or write the persistence for the jsessionid cookie into the rule I'm using to persist the cookie-disabled clients? If I stick with cookie insert, I can delete the persistence entry from the table for clients who return with cookies, and maintain the entries for clients who do not. If I use the jsessionid cookie, then I must maintain persistence entries for all clients.
