Tim is right about the liabilities of the Silver shifters, principally the loosening tension bolt and consequent breakage of the tension washer; and, also, their fragility when the bike falls over on them.
The Power Ratchet design used a locknut to hold the tension just right. But you can compensate for the lack of this on the Silvers by using blue Loctite. With that, mine stay adjusted indefinitely -- too much so, in fact, since I Loctited the left after making it too tight, and now it's hard to back it off. But I don't shift rings much. The absolute ne plus ultra of shifters would be a Silver with that part reinforced where the lever is cut back to accommodate the pawl; and with a locknut added to the mounting screw. Of course, the great liability of the PRs was that the locknut, proprietary, always got lost.
