Depends on a couple of things. Bicep, like all other muscles has a long and short head. It could be a case of working one more than the other. What types of curls are you doing? That'll determine which part of the bicep you are attacking.
I tend to use excersises that will attack both during a workout. My trick is also to superset the part of the bicep I'm working on to exhaust it that much more. I'll warm up, then 50% 10-12, 80-90% 5-6, then back to 50% until fail, wait 10 sec, then 50% to fail. 4-5 sets usually will exhaust the part of the bicep you are going after.
Like mine....but I am now seeing a trend of doing only one set of each type.
