Didn't use 4low at first, I also didn't disable the traction control or anything. I'll say this... it was much steeper than it looked and was very slick. I have quadra drive 2, i figured it would make it no problem, i probably didn't give it enough time to engage as i let off the gas pretty much as soon as it started to spin. Also this was really the first time i've driven on anything slick other than snow....
