Hydraulic riffles are necessary when you run for long periods and/or you have a lot of black sand. In a small scale operation where you clean up daily or every 2 days, it is not an issue

It's best to have a variety of different types of riffles, which is why the Gold Hog system is so well respected. Hydraulic riffles have their place but as stated above, it's just another style designed specifically for dealing with extremely high iron content. Magnets also have their place in this same situation.
