one nice thing about the crowsfoot line wrenches is that you put it on the end of a 3/8 breaker bar and you have a second line wrench for when you need two of the same size like when you are assembling lines and such
$$$, my friend, especially in this economy & the necessity for a rarely used item.
The above posts have swayed me to the 6-pt flare crowfoot, and will probably go SO since they have the best reviews insofar as not losing their shape under pressure.
While you gentlemen are at it, could you please see my thread earlier today: "About to purchase a Torque - Need your inputs," and please chime in, as the opinions on this forum are valued in guiding purchases. http://www.garagejournal.com/forum/showthread.php?t=37402
