Edit: To the OP, those are some very nice wrenches, I was responding below to another poster.
CountryRoad- Just curious what you are doing that you would get the FDP in anything over 1 1/4? Not trying to be the know it all police or anything but if I found myself in the situation where I'm saying "Man this 1 5/8 wrench just keeps slipping, I need a FDP" then I am using the wrong tool for the job. Wrenches that big are for snugging flanged connections or holding an opposing nut while your co-worker hangs off the 3/4 or 1 inch dr. ratchet. You can't exert the force needed (by hand) to properly tighten a 1 inch plus bolt with a combo wrench and its not very safe to try and loosen one that way either. Mabey you have a specific task where these are needed but a piece of advise from one wrench turner to another and working industrial maintenance for 12 years FDP that size is not practical IMO. If you are looking for large wrenches the thick handled round style or half round style from Wright are far more comfortable than the I-Beam handle from Snappy or anybody else for that matter and cheaper! End Rant
I'll second the Wright for larger sizes... they just can't be beat on price or comfort, period.
Furthermore, SO's prices are pretty reasonable on smaller sizes... but once you go larger, they just get absurd.
For instance, a 1-1/4 Snap on is $107, the same Wright is $33. There's no way in hell that SO is stronger than the Wright. Wright's wrenches are overbuilt specifically to be heavily abused in an industrial setting. Wright's "WrightGrip" is every bit as good as flank drive plus, I've used both.
If you're going for sheer finish quality and "shinyness" and most expensive, then the SO wins.
