After 5 years at Momentum, I say with confidence that Momentum has given me the best experiences of my life and made me a better skier.
Momentum's park is built for progression while offering features fit for any talent level. Their jumps range from 10-70+ feet. The jumps are predominantly step-ups/ overs meaning they are much safer than COC's predominantly step-down jump and thus offer you much more progression. As well, by having a private T-Bar that isn't shared by the public (COC's line's can be upwards of 20 minutes while Momentum's are consistently between 5) you will be able to get many, many more laps meaning much, much more progression. Attending Momentum also mean's that you will get access to a private air-bag, trampoline sessions every night, and water-ramp sessions nearly every day after skiing. As well, Momentum's amazing coach's (including, Wallisch, Dumont, Schlopy, Schiller, Woodsy, Dorey, Riddle, the list goes on and on) are eager to teach you ant trick you want to learn. Because your group gets a new coach each day, you get to learn each of their tips meaning that you you can learn double corks on slope from Wallisch one day and double corks in pipe from Simon the next, or rails from JF Houle.
After your day on the hill, you will down and go to activities with the same pros who were on hill with you that day. All of Momentum's activities are free and just to name a few: water-ramping, tramping, mountain biking, climbing, soccer/ basketball/ ultimate frisbee games,wakeboarding, ziplining, mon-ki-do, hiking and many more. You could learn cork 7's from Woodsy during the day and then shoot him in paintball during the afternoon.
Unlike COC, all of Momentum's meals are free and they are all at actual restaurants sprinkled across Whistler (not McDonald's and fast-food).
Momentum's hotel is in the center of Whistler Village, across the square from a grocery store and a minutes walk from ski-stores, candy stores, parks, poutine and every awesome thing you've ever seen condensed into one amazing village. With Momentum you are literally sconds away from all these amenities of Whistler where as at COC you stay in Whistler staff housing where you take a shuttle bus to get to the village. COC's housing is comprable to mediocre dorms where at Momentum you stay in a hotel with kitchens, beds, tv's, lofts in the rooms and a pool and suana area in the hotel as well as a camp lounge with video games galore.
The past five summers of my life have been the most amazing times of my life. I love momentum and I can promise you that you will too. If you have any questions please ask.
