RE: The Plettenberg nose exists. Anyone in the US tried it?
It's allowed, no matter what the CIAM/FIA, or whoever, states.
As long as Bernd Beschorner is still in the 2009 resultset, it's allowed. He used it and didn't get kicked out.
If they persist it's not allowed, than Bernd has to be taken out of the results for 2009/2010.
