I am usiing my Crew 8 20" now having gone to ARN (Sun) and will return to the USA from OSL (next week). At this point, I am quite satisfied with this choice for my needs and we'll see how it does 'down the road'.
As noted earlier in this thread, I first ordered a Crew 7 but decided that configuration of Crew 8 would have some advantages for my needs. I took delivery of the Crew 7 and then returned it at no cost to me.
