[Closed] Durable XT Hollowtech II bottom bracket?

I seem to be going through them too quickly at present, this may well be down to singlespeed use, I guess the best long term solution would be an alternative crank set/bottom bracket.

Can anyone recommend a durable bottom bracket to run with Hollwtechs that is readily available so I can get the bike back in action in the next day or two?

Also any thoughts on a longer term solution....Phil Wood square taper used in conjunction with??

Any thoughts greatly appreciated.
