Nice stash I’m jealous. I do rate maguras they are a top brake. Only got one set of mt7/mt8 but they have been brilliant. I rate the mt7 as the most powerful brake I’ve tried.Heck even the SLX/Deore version of this, M615 i think, worked like a charm. I still got two sets (M615 and M785) for a rainy day in the shed, brand new. Picked up for $140 a set (F+R) for the xt and $100 a set for the deore. Never letting them go even with the onset of four pots.
I rekon magura are the best brakes I've used though, just have to burn through my shimano stash first.
