BTW, you said the bottom bracket flexed 2 cm under torque? That's almost 7/8"! Are you sure you didn't mean 2 mm? What you were seeing is the bb shell moving.
I said 2cm. Not 2mm. It's probably less than 2cm, but it certainly is at least 7-8mm.
Oops. I just went out to the bike and put some torque into the crankset with the 8mm allen wrench and it only flexed a couple mm. I'll upload a video soon,
