Well, they are not on snow as you know it. Most races are held on very compacted and injected surfaces ... not snow. Look at some of the old video stock of races right up to the early 60's .... and they were not quite as formal, I'll stand corrected but one of the Western DH races "featured" a spruce that suddenly grew in the middle of the trail that made the favorite take a very different line. The tree was not there a few moments later. A wild rouge Christmas Tree escapes the slaughter pen at the tree farm? We will never know?
There is not enough information provided to take anything other than the wildest stab.
Like news reporting .... who, what, when, where and so on..
Blue is good, but where? Conditions vary. What HONEST level are you and cut the fluff and butter and stow MR EGO at the door. How do you ski?
It's much more than the skis .... IMHO most off the shelf SL style skis are just junk. Look at a Stockli ... from the Spirit Pro to the SC ... and you will find a well balanced performance ski that is well damped to handle icy stuff. The "off rack junk" (like Volkl and Atomic) got all jump/jittery when facing a bit of speed on icy fresh groomed cord. That is not good. That is not good at all.
I have put a few strong folks on SL type skis that are indeed performance skis like those SC's ..... my personal favorite for ice was 155 Stockli Race SL's ... lots of short turns locked in and smooth.
Good thinking and good luck.
