I can't understand one think over here.
Why you all advice so small boards here? his weight is 220(so as mine), and i believe he shold get no shorter than 165. better 167 or even more. I bet he is not going to corks in close future, so longer boards mean higher stability and speed.
And i think wider board is a must too. It's easier to ride in powder, or land the tricks with the wider one.
Look at the recommended riders weight for a boards, for example prior boards: All Mountain Freestyle 165 Wide weight range: 150-220. So his weight on the bigger end of this. Any freeride boards?? 170-230 recommends 170W Khyber.
And you recommend get a 160cm boards?
He'd be able to get to the bottom on any board, but it'd be more fun riding faster and more stable on a longer one.
Well, My opinion? I ride NS legacy-r 174, but i think LR 166, 170(better this one) would be enough, if there's not alot powder. Also check out another 166+ wide boards: Arbors, Ride, NS, Unity. They aren't cheap, but that would be so fun to go. And they would last 2-3 years.
