I prefer classic steel ones to aluminum myself and they all work _much_ better with some lube on the
cam. We oil every one with every bike/wheel build and it makes a noticeable difference!
Among major brands I haven't noticed a difference but they all clamp better than the new visible cam
aluminum models. Skewers on car racks are very often ( not your own I'm sure) subject to
corrosion/crud and lack lubricant, making them unsafe when you consider there's a windshield on the
car right behind you. . .
I read a good consumer guideline in the Raleigh manual years ago. It said you should see the imprint
of the lever on your palm for a few seconds ( not a haematoma!) after closing the skewer. Not a bad
thing to tell newbies IMHO. I do not have a better gauge of the required force, though
