Hi Dale, The higher quality of Wurzen AA does not mean that more lanolin was removed, just that it was processed differently. I don't know what is done differently, and I wouldn't expect that the company would give away any trade secrets by telling me or anyone else what the differences are. But you could try asking them. In my opinion, it stretches better then other felts I have used, which should make it more resilient.
