I may have interpreted information I've read but my understanding is that there is hardly any difference in how deep wire will get you VS braid while running dipseys. Besides flea problem with braid, which I find easy to deal, i don't believe there is much advantage to wire. I suppose the "sonic signature" mentioned by Chowder is a logical hypothesis but I've run both for many years and now strictly run braid due to convenience and my numbers never seemed to drop off. You may want to pick up a copy of the book at the link below- -I refer to it often when determining my spreads in all types of water bodies
