In reply to ford23:
I've only ever used BD skins, originally full nylon but now the nylon / mohair mix and they work just fine. One thing to watch out for if you're about to buy skins for your current skis then change skis is the shape and size you're going to trim the skins to. If the new skis are smaller than your current ones you may be able to trim them further and get a good fit but if not then your nearly-new skins will be too small (or at least the wrong shape) for your new skis. Much better to buy new skis & skins together if you can endure the current land-rover skins until the new skis arrive.
You can persuade a single pair of skins to fit a range of skis by making a cut along their centre line for most of the length of the skin, stopping 8 - 10 cm from each end. You can then fit the outer edge of the skin to the skis, leaving a strip down the centre of the ski with no skin on it. This does work but nothing like as well as properly fitting skins so I wouldn't recommend it.
