I'm just saying you're comparing fond memories to current reality, unfortunately.
The only 6900/61900s that appear to be readily available in MAX format are either Enduro or a few other no-name brands. If you compare items currently available, an Enduro MAX has a higher load rating than regular-fill bearings (see post #11 for data). Thus it's a better bearing for an MTB pivot application, especially in these small sizes.
I don't think the explorer is appropriate (angular contact) and I doubt it comes in sizes this small anyway given the increased complexity. Things have to exist and fit to be a viably better solution!
