ask larry narachi (lnarachi on here i believe). hes the only one i know that uses them in a pa taping application, and has tons of pulls from many different venues. if you want to hear a lot of 41s vs 41vs, there are many string cheese shows where larry ran the 41vs and john hart ran the 41s. though with capsules that directional it can be hard to not be apples to oranges, as pickup angle is more critical, imo. some guys use predefined patterns, others just point hypercards at the stacks, etc
