Harvest feels like a small cambered board, in other words, normal.
The Root feels like a longer board, is stable and is easy to chuck around.
I liked the Root so much I bought two of them. It's my daily driver for no new snow resort, park and all conditions at smaller resorts. It can handle all conditions.
The nug is a touch more floaty and fun in powder, but the root brings stability when carving, so I like it better.
