I have the Sonus DAS Pad Kit and I was just about to place an order for some Propel Pads. Will I be good just adding a blue polish and grey finishing pad or should I also add a green cutting pad? I would think that with the products I use I wont need any more cutting pads than the ones that came with the Sonus Kit. Does this sound right? BTW the only products I really use are Menzerna IP & FPII, AIO, Zaino/P21S/Souveran. Thanks!
