Hi teed, I can’t comment on the 9.0 but I’ve had a 6.0 for 5 months now and wouldn’t trade it! The spec is very good, but equally the ride is excellent. I initially had some concerns over the frame having come from an anthem, it felt very soft. However, after getting the suspension pressures sorted it rides ridiculously well. Climbs really well and descends super fast, it’s really helped my confidence, I’m taking on descents and jumps I wouldn’t have gone near before.
I’m only 5’10 so. Don’t know about how it works for a taller rider, although a friend of mine at that sort of height found a 29er fit better.
