I have been using mine for a little over six months and bought them for the word-of-mouth on how wonderful they where. The smaller to mid sizes I couldnt be happier with. They have really smooth action and great balance to them. This however is not so with the larger sizes, specifically 8-9 which have a tendency to walk unless they are placed without flaw, meaning all lobes must be perfectly parallel to one another. The larger sizes have way to little of a spring tension for my liking. The smaller sizes (.5 and 1) have a nice feel but I tend to get them stuck really easy. I think that may be from my own lack of experience with smaller sizes then the error of the cam itself.
