I've been playing Garlando for about 5 years and can tell you that bank shots do not come readily. But, once in a blue moon I will hit the ball hard from the two bar on an unintended angle or obliquely on the ball and the bank shot is incredible. It's incredbily fast (almost untracable) and stays on the table. But I just can't seem to replicate the shot when I wan't to.
I too have watched several Garlando vids on YT and haven't seen any banks. Aerials? As many as you want, but not banks. In fact, I haven't seen Collignon (an avid bank shooter from defense on several European tables) ever shoot a bank on a Garlando either.
