watervilles jumps are tough to beat....not saying loon doesnt have some nice jumps tho, they had a few really nice ones wen i was up there about 2 weekends ago. i deffinetly think if your a rail guy, go to loon. if your a jump guy, go to waterville. for me, i love waterville cuz i like the mtn itself and their park is just wicked fun. and loons lines get a little lengthy at times...
