Never skied with Weigle but I've been skiing with CMH for 30 years. And never done a snowcat trip although I have considered doing day trips and and several friends who have.
So, being totally bigoted and unqualified to advise you, GO FOR IT!
I saved all my coins a few years out of college and went for a "once-in-a-lifetime" trip to the Bugaboos in '72. The addiction caught on and I've never been able to (or had any interest in) stop it.
Other advice here is excellent. Make the most of the trip. Get in the best shape of your life. And be sure of your abilities.
Snowcat/heli comparison based on input from others and personal observations (my regular heli-ski partner has also done several snowcat trips):
1. The heli may be grounded for bad weather. I have sat an entire week in a blizzard and never gotten on the heli. And that was my vacation. And had another week where we only skied a couple of days. It is actually rather rare to get to ski all day every day without some down time due to weather.
The snowcat, on the otherhand, ALWAYS goes. I have heard of daily destinations being changed because of whiteout conditions but the cat is probably never really "grounded".
2. The cat is always "grounded". The number of runs either the cat or the heli can do in a day is limited by the speed of the slowest skier in the group and the speed of the "lift". Obviously the heli is faster than the cat. I don't know wht the vertical record for snowcat skiing in a day is but I would be surprised if it is much more than 15000 vertical feet. I've done 45000+ in a day on the heli and that is nowhere near a record. My biggest (and best snow) week ever was 240,000+ feet in 6 days (weathered out for one day).
3. How well your group "comes together" (third hand quote from nolo) will have a tremendous affect on your week. I've arrived at the beginning of weeks not knowing anyone else and left with lifelong friends. Compatibility of your group is crucial. If everyone is at the bottom watching the "head roll brothers" fall, get up, dig for skiis, fall, get up, dig for skiis, (repeat ad nauseam) down the last 500 vertical feet while other groups take "your" lifts it can really cut into your fun. And they aren't really having much fun either. Organize your group well. Compatible skiing ability can offset personality differences. If you can put together a heli sized group of compatable skiers you are less likely to pick up strays who are in compatable. As noted by Leroy, be honest about your ability when groups are formed.
4. Take the time to enjoy the skiing. Many people, especially on their first couple of trips, feel "pushed" by the helicopter. It moves so fast they feel they have to push to keep up. Remember, your there for the skiing, not the heli ride. But I guaranty you will never hear the "whup, whup, whup" of rotors again without it bringing incredible memories and the urge to crouch down...
