I bought a genuine set of these on ebay, and also a set of the replicas too. Both turned up today. I've had a quick play with the replicas tonight (probably won't throw the genuine ones in anger). I actually quite like them. They're a little lighter than I usually use and, despite the end cap on the shafts which is meant to prevent them to some degree, I found I was actually getting MORE deflections than usual because the flights themselves are much wider. They're also a little short so feel a bit different. But still feel pretty good and I enjoyed throwing them.
The knurled grip on the replicas is a little finer than on the originals (although I don't know how much variation the originals might have had), but other than that they seem a pretty authentic copy.
