Okay, the old pads came with 12.5cm diameter velcro, and the new ones come with 15.5cm of velcro. 3" more, and it covers the entire back of the pad minus a tiny little lip.
Now, that being said, when I had problems with mine, it was only the cutting and polishing pads that I had a problem with. They (Lake Country) swapped out both my cutting and polishing pads with no problem but didn't have a newly designed finishing pad *at that time.* I don't know if they have revised all of their pads since then or they are still shipping the old finishing pad with the set. Regardless, it seems the problem arises when a lot of pressure is applied to the pad, which you don't do with a finishing pad, so this shouldn't be a problem.
