Don't get me wrong, I have a lot of respect for all different forms of ski expression. I have respect for you. I enjoyed & envied your summer TR's, & can tell you are a very experienced skier.
I am not talking about skiing down a run that may host a DH. I am talking about racing on a prepared course, not just surviving it, but actually skiing it.
Like I said everyone has their own definition, so let's see if any of these fit your criteria.
Can it scare the Sh*t out of you, while you are still at the top scoping your line?
Can it kill or maim you if you make a miscalculation or loose focus?
Do you need to be in top physical condition to pull it off?
Does it take years of preparation & practice to even have a chance of finishing?
To me the Downhill is the ultimate test of technique, courage & skill that skiing has to offer. I have been around the ski world my whole life, & have hung with some of the original ski celebs who were initially labeled "extreme" & please believe me those guys are in awe of DH runs like Birds of Prey, the Hannenkahm & Bormio.
I think if you asked guys like Nobis, Tommy Moe or Daron Rahlves who do a lot of Big Mountain "extreme" stuff these days they would probably relay some DH racing experience as being as big an adrenaline rush.
I really haven't read most of this thread, so sorry if I am off track here.
