My friend ordered one week ago from that site.
We're heading to Solden next week, i can tell u after how it was.
But I heard very positive reviews (including angrysnowboarder
2.155W will be enough for freeride but still playfull.
3.Height play little to no role when choosing snowboard.
4.Slopes-completely fine, its midflexing board with camber in nose/tip with nice sidecut ...that's what I heard from reviews.
Powder-ull be fine there, its not powder specific deck but got rocker and 155W @ 140lbs is enough for having fun in powder.
Tricks-here it will shine - low swing weight for rotations, enough pop because of carbon in nose and tip , rocker and midflex for butters,jibs
5.155W is enough for you.
