slalomns are getting better, the one run that started right around 2:45 was really good (though the rest of the run was a bit rought, heh)
next course you walk I'd look at places where you can make 2-3 turns into one smooth arc, there are some spots in this course that would benifit from that technique
the last run was really good except the last corner
the only thing that I would've done differently was catch the rear of the car more smoothly, but that takes alot of "pitch and catch" to get down pat
