i like to do EZ Bar curls but i keep my palms facing outward... its kinda hard to explain, usually when doin EZ curls ur palms r sort of facing an inward angle toward the body, u need to grab the bar so they are both facing outward... if ur doin it right then it will feel weird and much harder but i totally pays off when tryin to make the peaks grow also i stick with 4 sets of 8 reps.... hope this wasnt too confusing GOOD LUCK
