The non nut flushes are most useful as backdoor flushes. Like say 1 of your suit comes but you have a wrap draw and get all in on the flop against 1 person and you hit the flush on the river it's likely to be good. But say you flopped a flush draw, and on the turn the flush hits and your in there with a couple of people, it's not likely a J or Q high flush is good, unless the A is on the board. But you should never draw to a nun nut flush, it's a disaster in Omaha. Having double suited non nut hands are good as secondary draws when you already have a set, straight or wrap draw.
