she is 5'11 and has been using a women's 155. A shop we visited recommended getting her on a men's board. Anybody have any experience with that?
She doesn't "need" a men's board. That recommendation makes me wonder if the shop didn't have anything in the size she would need in a women's board..
Does she want to size down from the 155? At her stats something around a 153 would probably be okay, especially if she's a beginner.
Just watch the waist width with her boot size.
