If you want to use a "+" wrench, make sure the ends are small enough to fit where they need to. Some of those wrenches have large ends and some wheels have narrow lug channels.
I just use a long 1/2" drive breaker bar with a short extension and a socket (a plastic-sleeved socket if the application calls for it). Anyone who doesn't already have a *good* breaker bar in the garage oughta have one, period, anyhow (OK, that's *IMO*

). And a torque wrench for tightening them back on properly. And a speed wrench for spinning the lugs on/off quickly. I honestly don't think anything is gonna beat the breaker/speedwrench/torque wrench combo for ease or speed unless you wanna use air power.
You can get this stuff pretty cheaply at Sears, etc., but I had a Craftsman breaker bar break on me (seriously :scared situation, the fractured yoke piece took a chip out of the concrete floor!) so from now on I'm sticking with my ancient Snap-On for that.
If anyone is really having problems with too-tight lugs....who're you letting work on your vehicles? I can't think of any passenger car lugs that are supposed to be much tighter than 100 pound/feet, and that's not all that much. Next time your mechanic pulls a wheel, check things out with a torque wrench and let the shop know if things aren't right.
