when stratton first had the power park set up, it was pretty primo. the key points were a) the flow, and b) the landings/lips to the booters. everything in it flowed, from the 2 jumps up top, to the option rail, to the option 4 booter line or rail line. when i skied it i felt an awesome sense of rythm, so that i could get into a groove kinda as i was skiing to get the confidence up. all of the jumps were good size: not too big, and not too small. regardless of the size, however, each had an appropriately sized lip and looong, steep landings. so when you were rolling through hitting the smaller jumps, it didn't feel like they had just been piled up a bit by the cats before they moved on to the bigger cooler jumps, each was important and had to be right.
i'd say now, though, they've let both the jumps and rails slide a bit since they first opened. the rails are the same as from the beginning, and need to be changed with something fresh, and the jumps have been eaten away a bit by the grooming. this could also be because of the open parks being built, im sure.
as for okemo, i really haven't ridden there much this year. i did ride the mountain heavily the last two seasons, and have been impressed. the jumps are usually nice, and rails (on nor'easter) are huge and challenging. given that i haven't skied nor'easter since the rebuild, i wasn't too impressed this year. i understand that the snow wasn't great, and that everyone had a late start, so i might have been expecting too much. but, the top three jumps were pretty poor - all different sizes, going from biggest to smallest, so it was hard to judge your speed, and the lips were pretty small for all of them. the rails i loved though - nice selection of new rails this year, and new and creative lips, like street style and multiple options (from all sides as well as right down the middle).
sorry i can't comment on the park after the rebuild, i haven't been back yet but plan to soon this week. one thing i noticed too is that nor'easter is a fairly rolly trail, which has to be tough to plan around in terms of flow and speed considerations. stratton has the advantage with a trail with a constant (although pretty flat) pitch. nor'easter's length makes up for it, though.
hope this has helped a bit, i'll let you know what i think after riding this week.
