So typically bigger is better right (in certain situations) but I am going to buy the swirl remover kit from Adams and I have the choice of the 7 inch pads or the 4 inch pads. Just curious if one is better than the other. Would the 4 inch give you a little bit more control over the 7? I am a newb and I have only used the DA on one car so far but the pads were very old and didn't produce the best results. Hoping to step up my game a bit on the second car. Thanks!
