Hi Jen, I'll be looking to get the DAS6 DA in the next couple of weeks. I'm not looking to correct at the moment so will be going for either Achilles Prep or Lime Prime. Do you have any view on these two? I'm can't really make up my mind but am leaning towards the Achilles Prep at the moment as it seems to have slight cut plus filler. What pad or pads would be best to use with these? Hex Logic 5.5" white?? Any others? Do these fit the 5" backing plate that comes with the DAS6? Thanks for any help.
