I know this is an older thread, but never saw anyone stat this.. I believe Biceps and Triceps need to on the same workout and super setted. If your wanting Size.
Something like this works very well.
Alt. DB Curls Super Setted with Rope Pressdows 3x15
Core Sets Rest /Pause DC Style but with 4 sets and total around 20reps
Preacher Curls Super Setted with Skull Crushers
Then I like to do FST-7 sets with.. (7x12)
Double Biceps Cable Curls Super Setted with a tricep Machine
Then on to Forearms
It's worked ok for me...
