Excellent article that needed to be written.
Could you go a little deeper into the part about triceps responding better to lower reps?
Well what more to be said 
Triceps tend to be a muscle built for strength and power because of it’s function (think of throwing a punch, or pushing away an opponent) as such because of its function an fiber makeup it responds best to lower reps (within reason, especially with isolation exercises) and heavier weights.
