I use one you all have not mentioned. Hornady Unique lube, which is (I think) just lanolin. Smells good, not oily, does not gum up my dies as Imperial has. I have used a concoction of Lee lube, water and alcohol to make a spray lube. I just don't like the water soluble stuff like Lee, as I have found it will rust your dies. Don't know about the One Shot, have not used it.
The Unique is really nice and easy, a little swipe between the thumb and forefinger and lube about 10 cases, a little goes a long way. Then just rub it in, helps dry cracked hands.
