Got a slim for a good price on the bay, seller of course described the quality as much better than it turned out when in hand, but it was a good deal so no real complaints. I do have a question, however. The click between the 4 and 5, and the 5 and 6 are different than the other clicks, they feel different and sound different. 5 is right in the middle of the wheel and is the common denominator out of the 2 different sounding clicks, is this common or to be expected? If I had to describe the sound and feeling the different clicks make it would have to be a looser/less firm click than the others in both sound and feel. Comments and thoughts appreciated, thanks in advance...
