I didn't really mean the cranks wobbled due to tolerance issues. Jut put it in there as another product of Profile's developing a wobble. Now, if they were made wrong. (what was it that made them wobble?, shell width i'm guessing.) Profile needing to send out spacers to increase the size of the axle width, is them needing to sort their tolerances. They also refused warranty on alot of hubs because of the wobble. Mid is probably more used due to it being an off-the-shelf bearing, the bearing being bigger will also mean it is less prone to blowing. Fly use spanish bb's still, and they continue to produce them to sell them too, as do a few other companies. There must be an advantage to them using spanish BB's on their frames. Probably because they can make money from selling the BB's to suit frames they sell, therefore increasing the profit they make as a company.
