OP, I used to do weighted chins as my primary bicep exercise but only because I had a back injury that I didn’t want to aggravate with BB curls. after I healed up and went back to BB curls, I was getting better bicep stimulation (SURPRISE!) despite using less weight (80-100 lb EZbar curls vs 45-60 lb weighted chins at ~190 lb BW).
also, if you want serious arm growth, give them their own day. before I strained my right bicep a month or so ago (stupid mixed grip on deads…), I was picking up about 1/4" a month on my arms, and that was with training them directly once a week at the end of the week.
also, what Prof X says about getting more out of the weight used is very true. sloppier form has its place, but IMO a majority of your reps should be fairly strict so that the target muscle actually does the bulk of the work.
