I think my thoughts are similar to @ski6jones. I think if you were to look at both sides of the argument you'd find, AS A RULE (I emphasize this because I know it will not be inclusive and people will disagree), the people most adamant about the tournament scene are those who either live on or near the water with a driver available multiple times a week. If they go to a tournament and miss a day of skiing it's no big deal cause Monday evening they know they'll be right back at it. Those more in favour of no tournaments would be ones like me who honestly don't know when they'll get their next set. Hopefully it will be this week but maybe not till next so if I have a free day, why spend the time and money on the possibility of only getting a pass or two.
For example, I skied today with a local skier/coach and got to my personal best (albeit a "practice score"). To be honest, I'd rather spend tomorrow trying to solidify and improve upon my pb but instead I'm going to ski in the only tournament within 4 hours of home where I may only ski 1 pass and be done, maybe not to ski again till next weekend.
I think those in the first category consider every day skiing to be "practice" whereas the second category would simply call it skiing
Having said all of this I am really looking forward to the tournament because, like many have said, there are a ton of good skiers and even better people who will be there and I enjoy catching up with them. I feel like it makes me a better skier to be able to ski in different atmospheres and under pressure. There's also a different level of accomplishment that I feel when I hit a pb in a tournament and opposed to "practice".
Just my thoughts. I know I'm not really committing to one side or the other, just trying to offer more insight on why there seems to be such a difference in opinions! Either way, as long as you're skiing the way you'd like to and are giving back to the sport whenever you can by helping those new to the sport and introducing people to it, we're going to collectively grow the sport. It takes all kinds.
