I have an ogilvy half pad, and it's great if your saddle is a bit too wide or something like that, though it does nothing if the saddle is a bit too narrow. The pad will compress in areas, and it does lessen any pressure points, but still make sure it doesn't cause any extra problems. If you add more bulk under an already tight fitting saddle, it will only cause extra pressure ( if you have a shoe that's a bit too small, does adding extra socks help?).
So! They are very nice pads, and if they work for the saddle you have I think you'll have some good luck with it. When in doubt, you could ask a saddle fitter what they would recommend
