Last time out, she rode a 158 Rome anthem on piste/hardpack and really liked it. Then spent 6 days splitting in pow on an old Voile split Decision Freeride 159.
It’s rockered, so it should be more manouevreable. If it rides like a playful 158, we should be grand. My concern with the 156, is if you take the pointy ends off that, you end up with a 152, which only 2cms longer than the 152 she’s already decided is too short… but if the rocker gives more float for the length… etc!
I’m 5’8″ 63kg. My boards are getting smaller. Used to ride 156, then 152. I was away a fortnight ago, riding powder the whole time on a 148 rocker freestyle board. No issues with sinking. In fact, lots of fun all the way.
Have a look at the nose shape. Some rocker shapes are a bit square (kinda the end squared off) rather than the traditional rounded shaped – means that they ride like they are about 4-6cm longer than they are (if you get what I mean).
