We don't use fly sheets, but the benefit that you get will depend largely on what type of flies you care about. Around here the most bothersome flies (to the horses) are the biting flies...bot flies that bother the legs and belly, and the horse flies (later in the summer). Covering the belly can help some for bot flies, but obviously don't help the legs. Fly sheets will help a lot with horse flies since the sheets are typically light colored and horse flies pursue large, dark colored objects. As with any covering, the down side is that you do have to watch for chafing/rubbing from the edges and straps.
Our horses just stay in their shelter when the biting bugs are bad (typically sunny, hot days between 10am and 4pm).
