Mred,
When I talked to Mike at VPI a few weeks ago concerning the rim drive he offered to send me the softer feet which he did. He also mentioned that they were working on a proprietory drive belt for the rim drive made of softer material which should provide smoother more forgiving drive. One of the reasons the rim drive needs to "settle in" is the belt smooths out with use. Presumably, the softer material should be less dependent on this. He said this may take a couple months to develop. This is my understanding of what he said at the time. If you want more information, give Mike a call at VPI(or e-mail). I'm sure he'd be happy to give you an update.
