In my opinion, that is too more than enough power for a roller intake system (assuming balls roughly the same size and weight there were in previous games). You are allocating two of the stronger motors you are allowed, not only to a single task, but a task that can typically be acheived with much less power. We used a single mini-bike in 06, and it worked fine (our hopper did jam on occasion though, but the intake had little to do with that). We probably could (and should) have used even a lesser motor (as the minibike could, on a full battery, actually launch the balls out of the top of the robot), and allocated the shooter the 2nd minibike motor.
