O.k., you have a couple problems here that can be easily solved. The first is that you are using large pads with a da with an inadequate polishing system. Your second problem, your 5.5 braking down, your cause is that you are using excessive pressure on the tool and causing heat which in turn is tearing up your pads.

Your solution is to use the 5.5 pads but with a better polish. The best polish to use with the da is the Megs twins. They cut a lot better and this in turn will cause you to use less pressure and tear up your pads. So in the end the pads are not the problem. Let me know if you have any other questions and I will steer you in the correct direction.
