just think about all those poor smith machines out there. Those 45lb plates just hanging off of them, taunting them, saying "hey look, people actually make gains off of me."
it's just not right.
Free the smith machine!!
And kos, if you want to hit your traps and rhomboids, you should be doing overhand bb rows or chin ups. Even close grip cable rows would be good. I definitely agree with you that angles matter, that's why it's even more important to step away from the smith because the smith locks you into one single plane of motion... And it's surely not the best plane.
