Do pros use them? or do they use the square taper,or isis?
I can assure you the installation is spot on.Got the proper tools and all.Crank bolts are pretty tight,It says about 130IN LB for those.That ain't gonna make one bit of difference in this situation anyway.Even uninstalled,all you have to do it try turning the bearing in the cup with your finger and you'll notice how tight it is.

BB casing?
