Thank you guys :) We've started carrying the Norgon Ambi-catch, it will be bundled with our selectors, and hopefully a new product that's almost made for it :) We thought about nickel boron coating the centers, which Spikes does with the OEM selectors we send them. For us, it added too much to the cost for something that didn't need fixing. Selector centers have been parkerized all this time, the only part that matters is the detent groove, but you can't just coat the detent groove... Given the shape and depth of our detent groove, and in conjunction with the KNS detent, it's smooth as is ;D
