I bought the 164 and have not ridden it yet. I will be riding it in japan in january and will update the review then.
First impression is good, its got a big fat nose with a really long gradual upsweep, it is not pointed like in the pics it is a completely round tip.
Mine has around 4mm camber as opposed to the 2mm stepchild says it has. The base looks like a golf ball with small dimples all over it. I have not waxed it yet so I cannot comment on how the base goes when I try to scrape it back but it seems there will be pockets of wax where the dimples are even though the factory wax job does not look like this.
