Has anyone had any experience with some of the "non-chain" traction aids? I have seen something called: Flex-Trax GoClaws in various outfitter catalogs like Cabela's. I see that they have their own website: http://www.flextrax.com/

It looks like an interesting device. I would not expect it to perform as well as chains, but, for ease of use, it seems like it might give you the extra traction, without the hassles of chains. I've thought about getting a new set of chains since I changed vehicles (and tire sizes) recently. When I saw these, I wondered if anyone has used them and might share their observations. Thanks.
