I have a pair of 07/08 watchlifes and I love them. They are stiff but it makes them super poppy and really fun on jumps. They don't butter the best but you still can flex em a bit. I'd get 173's if I were you, they are long (I rock 183's) but that makes them rail, really really fun jump skis.
Skied knee high pow at wolf creek this year too and they were way fun, width is good if you are mainly a park skier who sometimes gets a little bit of morning pow.
Mine are mounted at recommended, I was told from josh at jibij that unless you do 100% park to mount them at recommended. My slay everywhere.
