I don't know as much about cincta's, but given their adult size, should be alright.
Another thing to realize is that you'll have to add any pike at a decent size to be sure that it doesn't become lunch. Also make sure there is plenty of hiding places so that it can get away from aggressive fish.
Cinta are great pike. Grow to a good size, aren't too aggressive but will hold their own and they don't usually start things. At least that was my experience with them.
