I went with the
Dewhel kit like what Vehicluar DIY used as it seemed to be straightforward/no issues from his video, it was black, and didn't have an ugly clamp like the Rein kit (also $10 cheaper).
I used that money saved to buy an OEM 1" BMW clamp (07129952113) and a
5/16 brake line tube to upgrade the McDonald's straw while I'm in there (will be reusing the original ear-clamps)
None of my lines are busted (yet) but at 96k I am beginning to run on borrowed time, so might as well do them eventually
None of those are affiliate links btw
