Agreed [member=8955]Coen[/member], these were a second set that I purchased for just that reason. Sometimes you just need two of the same thing. I have a larger set of both fractional and metric combination wrenches, that are my main ones. I also keep a few that were just for a specific task, bought individually, and stored near the place where I use them.
The installers set is kind of a back-up for those "needing two" situations. I'm not a huge fan of ratcheting wrenches, but it has come in handy a few times.
I like the flat style with the sprag much better than the flip-lever ones. There is way less back-drag in the first place and you never have to strain for that extra little bit to get to the next tooth, that the clicking type have.
