I finally upgraded from my two year old HF DA to the lhr15, being an amateur I figured it would be good to learn on this and get the 21 mk2 later down the road and I couldn't pass up on the deal I got. All I can say is WOW! This thing is amazing compared to my old DA. The power, smoothness, overall feel,and the list goes on is on a whole different level from what I was used to. Only regret is waiting this long! Only thing left is to upgrade the pads I am using. I was wondering if anyone can recommend some good pads? I currently have cg hexlogic 5.5 pads but have been told the Rupes may delaminate them? I would like to stick to 5.5 inch pads if possible. Thank you all for any feedback and for the Rupes posts which influenced me in buying it!
