I think T47 is great, all the large axle benefits with none of the stupid press fit issues. It'll never take off properly as it's no use in a modern carbon frame but Chris King and white industries have both said they'll keep supporting it ad infinitum so I'm happy to run with it.
Every other industry in the world presses cartridge bearings into housings bored in the machinery framework. I'm not sure why bicycle makers have managed to turn such a well understood and widely used practice into such a clusterfuck.
Ah, I've just treated myself to some T47 taps and BB shells. #allthegearandnoidea
