Works great for me (a year in).
I’d been thinking about it anyway, but a bad experience trying to fit short Magura levers left with me some broken brakes. Had a couple of Zee levers kicking around so threw them at the problem. Initially with Shimano barbs and olives but switched them out for Magura ones as soon as I had chance to get any (no real functionak reason, just felt more logical).
Power is great, ergonomics are great, and they are super easy to bleed.
Hose – would gaffering the new hose to the old one and carefully pulling through not work?
