to be fair, ill admit that i havent been to killy this year since they got their big park. and ill admit that atti's rails are prettty weak compared to killington.
STill, you clearly havent been to attitash in the last few weeks. This past weekend, they had a full length jump line of: 15 ft step down, 50 ft step down option, 45-50 ft step up option, 60 ft step down option, and 55 ft step down. The flow is awesome, and while i can't speak for Killy, Attitash def has big floaty jumps this year
