The only ratching open ended wrench I have expierience with is these from Sears.
http://m.sears.com/craftsman-4-pc-metric-open-end-ratcheting-wrench/p-00921937000P They worked fine but the downside was that you needed at least 60° (one flat) of rotation before the "ratcheting" action would work. If you don't have that much throw at the end of your wrench then you are screwed. They also only work in one direction so don't think you can flip them to get a half flat at a time. For this single job I would stick with traditional combo wrenches. Specialty tools are fun when you have space and when the tool fits a recurring job perfectly.
