I think I'm on the path of an addict.
SK Flare Nut Set (Metric)
SK Flare Nut Set (SAE)
Snap On FD+ Reversible Ratcheting Set (Metric)
Snap On FD+ Combination Partial Set (Metric)
SK Stubby Combination Set (Metric)
Snap On High Performance Double Box Set (Metric)
Armstrong Double Open "Ratcheting" Set (Metric)
I'd still like a good set of stubby ratcheting wrenches and a good set of double box ratcheting wrenches, in metric. Not because I've ever come across a job that made me think "Man, if only I have one of those, I'd be more efficient", but just because I don't have those.
I've also thought about selling my partial FD+ (8-19mm minus 9, 16, and 18) set and using the money to buy a Wright Grip set since the ratcheting set is also FD+.
