By the way, nothing wrong with one or two master links on a fixed gear chain. I use two gearings, 46x17 for street, 53x17 for track (although I might get a 16 when I get my track wheels). Because I'm too cheap to have two chains (SRAM PC-68 by the way is a kickass chain, and not too pricey, $30-35), I add a little segment of chain and another master link to accomodate the bigger gearing. Works fine. Also, on some narrow chains it's not such a good idea to constantly punch pins in and out. Hell, some require you get a new pin. Your chain, however is a breeze to break and put back together, so don't worry about it. If you get stiffness, bend the chain side-to-side (not along the axis it naturally bends) around the link you replace to loosen up the plates. Sorry this is such a nonsensical chunk of text.
