Agreed!

Had a Shimano BB that kept "unscrewing" on my first outback trip (along the Savannah Way) because the LBS used the wrong screw-in ring (from a Truvalev). Had to get it spot welded in at an outback (Australia) machine shop at a mining operation.

Installed a square tapered PW after I returned and never looked back. Did several more outback (Australia) tours and the PW is still good as new.

Yes, expensive - BUT reliable.
