lol perhaps you're right lweaver, whatever works for the individual. But i'm an advocate of making sure my form is always on point. It's ok to cheat a bit in the last rep or two, but i see just way too many people just tryin to heave their weights up to the point where they're about to pop a hernia any second. Also, i didnt mean to imply that i'm doing light sets and just pumping em out, but rather, i'm lightening the weight enough so it doesn't throw my form out the window in the later sets. After a couple sets of controlled, perfect reps with constant tension, my biceps are jacked.
I find for me, that my biceps respond better to higher amount of volume creating more fatigue, as opposed to pressing movements. Pretty much any technique to extend the set(supersets, rest-pause, partials at the end of a set, etc). I find my biceps to also respond well to isometric loading, which is basically holding a pause during a movement.
But this is just my personal thoughts and concepts that have worked for me. For sure there will be ppl who disagree with me, and that's no problem. As a beginner though, i didnt focus on arms at all, i think i did 3 sets of preachers curls, once a week and that's it. My arms grew from rowing, deadlifting, pullups, and squats!
