Just wondering if you transferred all your Avios to QR keeping your BA avios at 10 for example, what would happen when reversals happen? I don't know if this has been discussed up thread. I imagine that you would go into a minus balance and the moment you transferred them back to BA to redeem them or earned some, you would effectively lose them then. Generally speaking it doesn't annoy me too much but was very angry when a TV purchase from Richer Sounds was reversed almost 3 years after purchase!
