I too run 2 TT bearings. Getting the bearings square appears to be more of a problem with the black TT .... mine was a little thinner than the silver ones I had used earlier. To try to sort this I tried to slide the bearings onto a small section of TT with a sticky tape cover. I managed this with one but couldn't do the second ..... so I then resorted to epoxy. I managed to get some of this onto the bearing shield .... but don't try to remove it until after it is dry. Using a small screwdiver it came off cleanly and the bearing is smooth. I think that if you try to wipe off wet adhesive it might get pushed into the bearing. For spacing I measured them out so that all the gaps were about 5 mm different 115/120/125mm if I recall correctly. Unfortunately I made a number of other upgrades at the same time so I cannot say that 2 bearings is worth it ..... but my Pro is silky smooth at the moment.
I must try my camera on it again .... good idea!!!
