Couple years ago surface were basiclly tooth picks but they picked up the slack a couple years ago and their skis have been doing pretty well. I have a pair of Watch life, which i use in the park, powder, frontside and tree runs. Sadly the first day i had them i was in a lift line a snow boarder came behind me super fast and hit my tail which chipped it. I epoxied it and its totally fine now.
I would recomend Surface because they are pretty cheap and dope skis.
Dont know a whole bunch about Moment, sorry
