For what its worth matkat, I don't think there are many pilots out there who have not sailed close to the wind at some stage in their career whether unwittingly or chancing their arm perhaps thinking they are not going to get called first thing on their standby in the morning etc etc.
The new limits are very prohibitive now and someone caught just over the limit can hardly be deemed drunk in my book but thats the world we live in now. It's just not worth the risk.
