I would recommend BE bearings, especially if you in colder climates or plan to continue using 10w60.
I myself live in colder climates and I will be using 5w50 from now on. I think 0w50 would be too thin and could cause vanos issues in extreme cases (no actual proof, just an educated guess here.)
At one point bmw north america actually released a new list of approved oils for the s85 and s65 which included 5w30. This only lasted for a few months, I read somewhere that bmw germany slapped bmw NA and they quickly removed that from the list. And the reasoning is that is almost like admitting they recommended the wrong oil from the get go and could ask for trouble (law suits and such). Not sure how much of this is true, but I did run 5w30 myself for a while and I did experience better cold starts, and I did like the way the engine ran also. I also didn't have to top up oil at all.
But I then went back to 10w60 while trying to solve my vanos issues. Then my rod bearing job came up, and I found a spun bearing.
