Most people aren't going to get big biceps from doing chins.
If you want to look like a bodybuilder, train like one....
I've experimented with this quite a bit and could beat the subject to death, but since this forum is more about minimalism and abbreviated training than building the biggest gunz in the neighborhood, I'll keep it short. On one hand, chances are someone who is not into bodybuilding probably will almost certainly put on size if he does max effort chins (especially weighted) every week for six to eight weeks, but they are not going to be as impressive as those built by a sequence of heavy barbell curls, incline DB curls, and concentration curls with at least one set of each taken to failure.
This has been my observation, too.
If you want to get SUOPERSWOLE7000 it's NOT chins or curls, it's chins AND curls.
